Introduction to Gases and Boyle's Law

True or False. The initial volume is lower than the final volume thus, the initial pressure is higher than the final pressure.

• True

Suppose that pressure remains constant, what will happen to temperature if volume is increased?

• Temperature will increase

• Temperature will decrease

True or False. High temperature allows gas particles to move more rapidly, thereby increasing pressure.

• True

• False

In BOYLE'S LAW, when Volume increases then Pressure must...

• Increase

• Decrease

A sample of hydrogen gas (H₂) has a volume of 4.0 L and a pressure of 1.0 atm. What is the new volume if the pressure is increased to 2.0 atm at constant temperature?

A 10.0 L balloon contains helium gas at a pressure of 655 torr. What is the new pressure when the volume expands to 20.0 L at constant temperature?

The volume of the air in a person’s lungs is 615 ml at a pressure of 760 mmHg. Inhalation occurs as the pressure in the lungs drops to 752 mmHg. At constant temperature, to what volume did the lungs expand?

Imagine that a gas is inside a cylinder with a movable piston. If the volume of a gas is 2.0L when the pressure is 760 torr; what is the volume of the gas if the pressure is halved?

To compress nitrogen at 1 atm from 750 mL to 500 mL, what must the new pressure be if the temperature is kept constant?
