At a constant pressure, the volume decreases.  What happens to the temperature?

• increases
• decreases
• stays the same

At a constant volume, the pressure increases.  What happens to the temperature?

• increases
• decreases
• stays the same

At a constant temperature, the volume decreases.  What happens to the pressure?

• increases
• decreases
• stays the same

Which of the following is NOT a part of Kinetic Molecular Theory?

• Gas particles have mass and occupy space (the individual particles have volume)
• Gas particles do not have mass and occupy space (the individual particles have volume
• Gas particles move in straight lines
• The more heat energy the gas particles have, the faster they move

At a constant pressure, the volume decreases.  What happens to the temperature?

• increases
• decreases
• stays the same

Under which of the following conditions do REAL gases behave most like IDEAL gases?

• High pressure and high temperature
• High pressure and low temperature
• Low pressure and low temperature
• Low pressure and high temperature

At a constant temperature, pressure increases.  What happens to the volume?

• increases
• decreases
• stays the same

Gases of the same volume contain the same number of molecules.  This is the description of:

• Boyle's law
• Dalton's law
• Charles' law
• Avogadro's law

What is diffusion?

• the ability of one gas to mix with another gas.

• the rate at which a gas flows through the air.

• an explosion of gases.

• the ability of a gas to move from a high pressure to a low pressure.

At a constant pressure, the volume decreases.  What happens to the temperature?

• increases
• decreases
• stays the same
