Behavior of Gases Test

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 less than the space between liquid or solid particles.

• The volume of a gas’s particles is small compared to the overall volume of the 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.

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.

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

• It increases.

• It decreases.

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

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.

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.

If 4 moles of gas are added to a container that already holds 1 mole of gas, how will the pressure change inside the container?

• The pressure will be five times higher.

• The pressure will double.

• The pressure will be four times higher.

• The pressure will not change.

Why does air escape from a tire when the tire valve is opened?

• The pressure outside the tire is lower than the pressure inside the tire.

• The pressure outside the tire is greater than the pressure inside the tire.

• The temperature is higher outside the tire than inside the tire.

• There are more particles of air outside the tire than inside the tire.
