The Relationship between Gas Pressure and Volume at Constant Temperature

What happens to the pressure of a gas when the volume of its container is increased at constant temperature?

• The pressure fluctuates randomly.

• The pressure increases.

• The pressure remains the same.

• The pressure decreases.

Which equation represents the relationship between pressure and volume for a fixed mass of gas at constant temperature?

• P + V = constant

• P - V = constant

• PV = constant

• P/V = constant

In the example problem, what is the final pressure of the gas after expansion?

• 10,000 Pascal

• 20,000 Pascal

• 40,000 Pascal

• 30,000 Pascal

What effect does compressing a gas with a piston have on its internal energy?

• It has no effect on the internal energy.

• It causes the internal energy to fluctuate.

• It increases the internal energy.

• It decreases the internal energy.

What happens to the temperature of a gas when its internal energy is increased by doing work on it?

• The temperature remains constant.

• The temperature becomes unpredictable.

• The temperature increases.

• The temperature decreases.
