The Gas Laws.

What does the constant bombardment of gas molecules against the inside walls of a container produce?

• temperature

• pressure

• density

• diffusion

Convert the pressure 1.30 atm to kPa.

• 2 kPa

• 115 kPa

• 132 kPa

• 245 kPa

Standard pressure is exactly

• 1 atm

• 760 atm

• 101.3 atm

• 760 kPa

The volume of a gas is 400.0 mL when the pressure is 1.00 atm. At the same temperature, what is the pressure at which the volume of the gas is 2.0 L?

• 0.5 atm

• 5.0 atm

• 0.20 atm

• 800 atm

A sample of oxygen occupies 560. mL when the pressure is 800.00 mm Hg. At constant temperature, what volume does the gas occupy when the pressure decreases to 700.0 mm Hg?

• 80.0 ml

• 490 ml

• 500 ml

• 640 ml

The volume of a gas is 5.0 L when the temperature is 5.0ºC. If the temperature is increased to 10.0ºC without changing the pressure, what is the new volume?

• 2.5 liters

• 4.3 liters

• 5.1 liters

• 10.0 liters

Why could the pressure of a sample of gas at a constant volume fall 75 mm Hg?

• the container exploded

• the temperature increased

• the temperature decreased

• the volume increased

On a cold winter morning when the temperature is –13ºC, the air pressure in an automobile tire is 1.5 atm. If the volume does not change, what is the pressure after the tire has warmed to 15ºC?

• -1.5 atm

• 1.7 atm

• 3.0 atm

• 19.5 atm
