How is gas pressure produced in a closed container of a gas?

• Collisions between the particles of the gas
• Collisions between the particles of the gas and the walls of the container
• Collisions between the particles of the walls of the container
• The gas exerts a force on the walls of the container.

Identify the three factors that affect gas pressure.

• Temperature
• Number of particles
• Volume
• Type of gas
• Type of container

If the temperature of a gas increases, then its pressure

• increases.
• decreases.
• stays the same.

If the volume of a gas is increased, then its pressure

• increases.
• decreases.
• stays the same.

If the number of particles of a gas increases, then its pressure

• increases.
• descreases.
• stays the same.

A gas is heated from an unknown temperature to 560 K. If the original volume was 90 L, and the new volume is 95 L, what was the original temperature of the gas? The pressure of the gas is kept constant.

• 15.27 K
• 591.11 K
• 4788000 K
• 530.53 K

A gas with an unknown pressure has its container expanded. The original volume of the container 15 L, and the new volume is 45 L. If the new pressure of the gas is 42 Pa, what was the original pressure of the gas? The temperature is kept constant.

• 126 Pa
• 14 Pa
• 16.07 Pa
• 0.06 Pa

The state of matter in which a material has neither a definite shape nor a definite volume is

• solid.
• liquid.
• gas.
• plasma.
