Which of these changes would NOT cause an increase in the pressure of a contained gas?

• The volume of the container is increased.

• More of the gas is added to the container.

• The temperature is increased.

• The average kinetic energy of the gas is increased.

Why does airescape 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.

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

• The pressure increases.

• The pressuredoes not change.

• The pressure will decrease.

• The pressure cannot be predicted.

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.

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 o f a gas's particles is small compared to the overall volume of the gas.
