Combined Gas Laws and Kinetic Molecular Theory

If a balloon is heated, what happens to the pressure of the air inside the balloon if the volume remains constant?

• It increases

• It stays the same

• It decreases

• The change cannot be predicted

Why is a gas easier to compress than a liquid or a solid?

• Its volume increases more under pressure than an equal volume of liquid does

• Its volume increases more under pressure than an equal volume of solid does

• the space between gas particles is much greater than the space between liquid or solid particles

• the size of gas particles is great

If the volume of a container of gas is reduced, what will happen to the pressure inside the container?

• the pressure will increase

• the pressure will not change

• the pressure will decrease

• the pressure depends on the type of gas

Why does the pressure inside a container of gas increase if more gas is added to the container?

• there is an increase in the number of collisions between particles and the walls of the container

• there is an increase in the temperature of the gas

• there is a decrease in the volume of the gas

• there is an increase in the force of the collisions between the particles and the walls of the container

The volume of a gas is doubled while the temperature is held constant. How does the gas pressure change?

• It is reduced by one half

• It does not change

• It is doubled

• It varies depending on the type of gas

If a balloon is squeezed, what happens to the pressure of the gas inside the balloon?

• It increases

• It stays the same

• It decreases

• The pressure depends on the type of gas in the balloon

What happens to the pressure of a gas inside a container if the temperature of the gas decreases?

• the pressure increases

• the pressure does not change

• the pressure decreases

• the pressure cannot be predicted

What happens to the temperature of a gas when it is compressed?

• the temperature increases

• the temperature does not change

• the temperature decreases

• the temperature becomes unpredictable

When the Kelvin temperature of an enclosed gas doubles, the particles of the gas...

• move faster

• strike the walls of the container with less force

• decrease in average kinetic energy

• decrease in volume

A gas occupies a volume of 2.4 L at 14.1 kPa. What volume will the gas occupy at 84.6 kPa?

• 497 L

• 2.5 L

• 14 L

• 0.40 L
