ChemH Gases Review

All of the following are properties of ideal gases except:

• Small amounts of energy are lost during collisions between gas molecules

• Volume occupied by molecules is negligible compared to the volume occupied by the gas

• Gas molecules do not interact with each other except during collisions

• Gas molecules do not interact with each other except during collisions

Gases found in the environment are most likely to exhibit properties similar to that of ideal gases under conditions of:

• low temperatures and high pressures

• high temperatures and high pressures

• high temperatures and low pressures

• low temperatures and low pressures

Which of the following would increase the (gas) pressure of a system?

• Increase the Temperature
• Pump in more gas
• Decrease the volume

If the temperature of a gas decreases, the pressure...

• Decreases

• Increases

• Does not change

Which container will have lower pressure?

• left
• right

The kinetic molecular theory of matter states that all of the particles that make up matter are constantly

• growing

• shrinking

• crying

• moving

At higher temperatures...

• particles in an object have less energy
• particles in an object move faster
• a gas contracts
