Read each question carefully and answer to the best of your ability. Show all your work for calculations.

1. Which gas variable is a measure of the average kinetic energy of the gas particles?

a

Pressure

b

Volume

c

Temperature

d

Amount of gas

2. If the volume of a gas is decreased while keeping the temperature and amount of gas constant, what happens to the pressure?

a

It increases

b

It decreases

c

It stays the same

d

It first increases then decreases

3. According to Boyle's Law, pressure and volume are   proportional when temperature and amount of gas are constant.

4. Charles's Law states that at constant pressure and amount of gas, volume and temperature are   proportional.

5. The SI unit for temperature in gas law calculations is  .

6. Increasing the temperature of a gas will decrease its pressure if the volume is kept constant.

T

True

F

False

7. The number of moles of a gas is directly proportional to its volume at constant temperature and pressure.

T

True

F

False

8. Describe the relationship between pressure and temperature for a fixed amount of gas in a rigid container.

9. Explain why a hot air balloon rises, relating it to gas variables.

10. A gas occupies a volume of 2.5 L at a pressure of 1.0 atm. If the pressure is increased to 3.0 atm while keeping the temperature constant, what is the new volume of the gas?
