Quiz 1: Gas Laws and KMT Review

A hypothetical gas that perfectly fits all the assumptions of the kinetic molecular theory is known as:

• a real gas

• an ideal gas

• an imaginary gas

• a perfect gas

Select the following statements(s) that are TRUE about the volume of a gas:

• Most of the volume is empty space.

• The volume is occupied by particles in continuous, rapid, random motion.

• The volume is about 10 times greater than that occupied by an equal number of particles in the liquid or solid-state

• The volume can be easily changed, as gases do not have a definite volume

When gas molecules collide, kinetic molecular theory predicts:

• the collisions are inelastic and there is less kinetic energy after the collision

• the collisions are perfectly elastic and there is more kinetic energy after the collision

• the collisions are so hard the gas molecules break apart

• the collisions are perfectly elastic and there is no net loss of kinetic energy

At higher temperatures, the particles of a gas:

• move slower and hit the walls of their containers less often.

• move faster and hit the walls of their container more frequently.

• move faster and hit the walls of their container less frequently.

• don't move at all and don't hit the walls of their container.
