Unit 11 - Gases

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

• 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 containing more molecules have a larger volume. This is the description of:

• Boyle's law

• Dalton's law

• Charles' law

• Avogadro's law

What is true of molecules of gas that are exposed to heat in a fixed volume container?

• They move faster and they cause the pressure to increase

• They move slower and pressure will decrease

• The volume increases and pressure increases

• The volume decreases and the pressure decreases.

What is the value of STP?
