Question 1

Which statement best describes the kinetic molecular theory of gases?

Accepted Answer

Gas particles move randomly with high velocities and have negligible attractive forces.

Question 2

Which property of a gas increases the kinetic energy of its particles?

Accepted Answer

Temperature

Question 3

A gas sample is heated in a rigid container. What happens to the pressure inside the container?

Accepted Answer

Pressure increases because molecules move faster and collide more often.

Question 4

Which of the following is NOT a property that describes a gas?

Accepted Answer

Color

Question 5

What is the correct relationship for Boyle's Law?

Accepted Answer

$$P_1V_1 = P_2V_2$$

Question 6

If the pressure on a 6.0 L sample of gas is doubled at constant temperature, what will be the new volume?

Accepted Answer

3.0 L

Question 7

Which equation represents the relationship described by Charles's Law?

Accepted Answer

$$V_1$$/$$T_1$$ = $$V_2$$/$$T_2$$

Question 8

A balloon has a volume of 2.0 L at 300 K. If the temperature increases to 600 K at constant pressure, what is the new volume?

Accepted Answer

4.0 L

Question 9

Which of the following is true about the behavior of gases compared to liquids and solids?

Accepted Answer

Gases are less dense and easier to compress than liquids or solids.

Question 10

What is the SI unit for measuring pressure?

Accepted Answer

Pa

Question 11

At higher altitudes, atmospheric pressure is:

Accepted Answer

Lower than at sea level

Question 12

Which of the following gases is NOT found as a major component in air at room temperature?

Question 13

If the temperature of a gas is increased at constant volume, what happens to the pressure?

Accepted Answer

Pressure increases

Question 14

Which formula correctly expresses the definition of pressure?

Accepted Answer

$$P = \frac{force}{area}$$

Question 15

A gas sample has a pressure of 1.00 atm and a volume of 2.0 L. If the pressure is increased to 4.00 atm at constant temperature, what is the new volume?

Accepted Answer

0.5 L

Question 16

Which of the following statements about the kinetic molecular theory is correct?

Accepted Answer

Gas particles move in straight paths and are in constant motion.

Question 17

Which property of a gas is measured in moles?

Accepted Answer

Amount (n)

Question 18

If the volume of a gas decreases at constant temperature, what happens to the pressure?

Accepted Answer

Pressure increases

Question 19

Which of the following is a direct relationship according to the gas laws?

Accepted Answer

Volume and temperature (Charles's Law)

Question 20

Which of the following is true about the volume of a gas in a flexible container?

Accepted Answer

Adding more particles increases the volume.
