Use the drop-down menus to complete the sentences describing what happens when the temperature of a fluid
increases.
The kinetic energy of the molecules
The speed of the molecules
The density of the fluid
The fluid
when the temperature of a fluid increases the kinetic energy of the molecules increases.
Explanation:
when there is a change in liquid temperature then there will be changes in its properties especially in the (KE) kinetic energy of molecules and the density of the fluid. Due to the addition of the heat kinetic energy of the fluid molecules as it gains the heat, the intermolecular movement increases so there will be in the increased collision between the molecules which results in breaking the intermolecular force. Whenever the heat is applied to any matters nature is to tend to expand so the fluids also expand which results in the decrease in the density of the liquid. And also due to the increases in the kinetic energy, the speed of the fluid also increases.According to the kinetic-molecular theory, when the temperature of a fluid increases:
1. The kinetic energy of the molecules increases.
2. The speed of the molecules increases.
3. The density of the fluid decreases.
4. The fluid rises.
The kinetic-molecular theory of gas states that gas molecules typically exhibit a perfectly elastic collision and are always in a state of continuous (constant) random motion.
This ultimately implies that, the average kinetic energy of gas molecules is directly proportional (highly dependent) to both the temperature and speed of the molecules and inversely proportional to its density in accordance with the kinetic-molecular theory.
Deductively, we can conclude that the following happens when the temperature of a fluid increases:
The kinetic energy of the molecules increases.The speed of the molecules increases.The density of the fluid decreases.The fluid rises.Read more on kinetic-energy here: brainly.com/question/11640748

Answer:
It is dangerous to combine alcohol and other drugs because Combining them may cause a more intense effect than just taking one drug at a time and the effect can be unpredictable.
Explanation:
hope this helps
brainliest is appreciated... :}
Final answer:
Combining alcohol with other drugs is hazardous due to the increased risk of significant CNS depression, leading to serious consequences such as respiratory failure or death. Compounding tolerance and severe withdrawal symptoms highlight the dangers of physical dependence on these substances.
Explanation:
It is dangerous to combine alcohol and other drugs because such combinations can lead to additive or synergistic effects that intensify the impact on the central nervous system (CNS). For example, alcohol and barbiturates both depress the CNS, potentially resulting in enhanced sedative effects which may escalate to severe respiratory depression, coma, or death. Alcohol also impairs motor control, judgment, and cognitive functions, and when combined with other CNS depressants, these effects worsen, creating significant risk for injuries or fatal accidents.
Additionally, chronic alcohol consumption can lead to increased tolerance, meaning that higher doses are needed to achieve the same effect, which can be particularly dangerous when other substances are involved. Withdrawal symptoms from alcohol or other depressants can be severe and even life-threatening, requiring medical supervision during the detoxification process. This is indicative of the physical dependence that users of depressants could develop over time.

How many grams are in 4.23E44 particles of PbO2
1.679 × 10²³ g of PbO₂ is present in 4.23×10⁴⁴ particles of PbO₂.
Explanation:
First the number of particles is converted into moles by dividing it by the Avogadro's number and then moles multiplied by the molar mass, we will get the mass of PbO₂ in grams.
4.23×10⁴⁴/ 6.022×10²³ = 7.02×10²⁰ moles
Now we have to multiply this by the molar mass of PbO₂, that is 239.2 g/mol, we will get the mass in grams.
7.02×10²⁰ moles × 239.2 g/mol = 1.679 × 10²³ g of PbO₂

3.01 x 10^23 atoms of rubidium
Answer:
0,5 mole
Explanation:
Because n = N/Nₐ, n(Rb) = 0,5 mole
One mole of every element contains 6,022045 × 10²³ atoms, so 3,01 × 10²³ atoms of rubidium is half mole.
To solve this we must be knowing each and every concept related to mole. Therefore, 3.01 x 0²³ atoms of rubidium contains 0.499moles.
What is mole?A mole is merely a measuring unit. In reality, it is one of its International System of Units' seven foundation units. When current units are insufficient, new units are created.
Chemical reactions frequently occur at levels where employing grams would be inappropriate, but using absolute quantities of atoms/molecules/ions would also be misleading.
For all practical reasons, one mole of a substance in grams is nearly equal to 1 molecule for the compound per daltons.
Mathematically,
mole =given number of atoms ÷ 6.022×10²³(Avogadro number)
given number of atoms=3.01 x 0²³
substituting all the given values in the above equation, we get
mole =3.01 x 0²³ ÷ 6.022×10²³(Avogadro number)
=0.499moles
Therefore, 3.01 x 0²³ atoms of rubidium contains 0.499moles.

What term means that the state of matter stays the same
Answer:
answer is solid
Explanation:
solid always is hard and can never change yet liquid and gas can move
The term 'phase' refers to the state of matter staying the same, and there are three main phases: solid, liquid, and gas. In a solid, the particles are in fixed positions and maintain a fixed volume and shape. The law of conservation of matter states that the total amount of matter remains constant during phase transitions.
The term that means the state of matter stays the same is phase. Matter exists in one of three main states, namely solid, liquid, and gas. In the solid phase, atoms or molecules do not have enough energy to move past each other and are in fixed positions with strong intermolecular forces; thus, they maintain a fixed volume and shape. The liquid phase has atoms or molecules that are constantly in contact yet have enough energy to move freely relative to one another, allowing the liquid to take the shape of its container while maintaining a definite volume. The gas phase is characterized by particles that are separated by relatively large distances and that fill the volume of their container.
In any closed system, the law of conservation of matter dictates that no detectable change in the total amount of matter occurs during the transition from one phase to another. Thus, when matter undergoes a phase change, its state may alter, but the total quantity of matter remains constant within a given system.
Which of the following set ups which converts centimeters to fit
Answer:
The fourth one down
Explanation:
It is the only setup in which the units of "cm" and "in" cancel correctly and give the desired units of "ft."
The second one down has the correct units but the wrong conversion factor for converting centimetres to inches.
The student is asked to use dimensional analysis for unit conversion within the metric system, such as converting meters to centimeters using a ratio or conversion factor.
Explanation:The question asks for the conversion of centimeters to fit, which appears to be a typo and should likely refer to converting measurements within the metric system. Specifically, the task involves applying dimensional analysis to convert lengths from one unit to another, such as meters to centimeters or vice versa.
Steps for Conversion Using Dimensional Analysis
Identify the provided measurement and its unit.
Determine the unit you need to convert to.
Set up a conversion factor, which is a ratio representing the relationship between two units.
Multiply the given measurement by the conversion factor to get the answer in the desired unit.
For example, to convert 1.5 meters to centimeters, you set up the proportion: 100 cm/1 m = x cm/1.5 m. By cross multiplying and solving the proportion, you find that x = 100 × 1.5 cm, which equals 150 cm.

If 13.5 L of Nitrogen gas react with 17.8 L of Hydrogen gas at STP, according to the following reaction, what mass of ammonia will be produced?
The reaction between nitrogen and hydrogen produces ammonia according to the equation N2(g) + 3H2(g) = 2NH3(g). Calculating stoichiometries in terms of volumes and moles shows that having 13.5L of nitrogen gas and 17.8L of hydrogen gas at STP will produce approximately 20.47g of ammonia.
Explanation:The subject of this question is the stoichiometry of the reaction between nitrogen gas and hydrogen gas to produce ammonia. This is defined by the balanced chemical equation N2(g) + 3H2(g) = 2NH3(g). According to this equation, one mole of nitrogen gas reacts with three moles of hydrogen gas to form two moles of ammonia.
Given that one mole of an ideal gas occupies approximately 22.4 L at STP (Standard Temperature and Pressure), the moles of nitrogen and hydrogen present in the scenario can be calculated by dividing the given volumes by 22.4. This gives us roughly 0.602 moles of Nitrogen and 0.795 moles of Hydrogen. The limiting reagent in this reaction is Nitrogen, because it would require at least 1.806 moles of Hydrogen to fully react with the Nitrogen present. Hence, the reaction will only proceed until all the Nitrogen is consumed.
This would form roughly 1.204 moles of ammonia (double the amount of Nitrogen as per the stoichiometry). The molar mass of ammonia given is 17 g/mol. So, multiplying the formed moles of ammonia by its molar mass gives us the total mass of produced ammonia, which is about 20.47 g.

9.04 grams of ammonia will be produced.
If 13.5 L of Nitrogen gas react with 17.8 L of Hydrogen gas at STP, according to the reaction N₂ + 3H₂ → 2NH₃, we need to determine the mass of ammonia produced.
Step-by-Step Solution:
1. Identify the limiting reactant:
Using the balanced equation, 1 volume of N₂ reacts with 3 volumes of H₂. To react with 13.5 L of N₂, we need:
3 × 13.5 L = 40.5 L of H₂
Since we only have 17.8 L of H₂, Hydrogen is the limiting reactant.
2. Calculate the volume of NH₃ produced:
From the stoichiometry, 3 volumes of H₂ produce 2 volumes of NH₃. Hence, 17.8 L of H₂ will produce:
[tex]\frac{2}{3} * 17.8L[/tex] = 11.87 L of NH₃
3. Convert the volume of NH₃ to mass:
At STP, 1 mole of gas occupies 22.4 L. First, find the number of moles of NH₃:
[tex]\frac{11.87L}{22.4 L/mol}[/tex] = 0.5308 moles of NH₃
Now, calculate the mass of NH₃ using its molar mass (17.031 g/mol):
0.5308 moles × 17.031 g/mol = 9.04 grams
Therefore, the mass of ammonia produced is 9.04 grams.

Which is true with respect to the kinetic energy of a molecule?
O A.
it is the lowest at low temperatures
B.
it increases at low temperatures
C.
it is the same at all temperatures
D.it is the lowest at high temperatures
Answer:
A. it is the lowest at low temperatures
Explanation:
At low temperature the kinetic energy of a molecule is low. The kinetic energy is directly proportional to the temperature of the molecule. The kinetic energy of a molecule increases with the increase in the temperature that energize the molecules of a substance and makes them to move faster than before.
As the kinetic energy is proportional to temperature so it does not increase with decrease in the temperature (low temperature). The kinetic energy varies with the change in the temperature and it is not same at all temperature. The kinetic energy is highest at high temperature. Thus, option A is correct.

The volume of helium in a blimp is 6.28 × 109 milliliters. The density of helium in the blimp is 0.1786 . Find the mass of the helium in the blimp.
Hey There!:
Density = mass / volume
Density of helium in the blimp = 0.1786 kg/m³
Volume of helium in the blimp = 6.28 x 10⁹ mL
converting the volume in m³ :
1 m³ -------------------------------- 1 x 10⁻⁶ m³
Volume( m³ ) -------------------- 6.28 x 10⁹
Volume ( m³ ) = ( 6.28 x 10⁹ ) x 1 / ( 1 x 10⁻⁶ )
Volume ( m³ ) = ( 6.28 x 10⁹ ) / ( 1 x 10⁻⁶ )
Volume ( m³ ) = 6280 m³
Therefore:
D = m / V
0.1786 = m / 6280
m = 0.1786 x 6280
m = 1121.608 g
converting in Kg :
1 kg ------------------ 1000 g
?? --------------------- 1121.608 g
mass = 1121.608 x 1 / 10000
mass = 1121.608 / 10000
mass = 1.12 x 10⁶ g
Hope that helps!
Final answer:
To find the mass of helium in the blimp, multiply the volume of helium ([tex]6.28 * 10^9[/tex] milliliters) by the density (0.1786 g/mL). This results in a mass of approximately [tex]1.121768 * 10^9[/tex] grams.
Explanation:
The question asks us to calculate the mass of the helium in the blimp given its volume and density. To find the mass, you need to use the formula: mass = volume × density.
In this case, the volume of helium is 6.28 × [tex]10^9[/tex] milliliters and the density of helium is 0.1786 grams per milliliter. So, you would calculate the mass as follows:
mass = 6.28 × [tex]10^9[/tex] mL × 0.1786 g/mL
mass = 1.121768 × [tex]10^9[/tex]grams
The mass of helium in the blimp is therefore approximately 1.121768 × [tex]10^9[/tex] grams.
