Introduction to Gases

At a constant temperature, the volume of a container is increased. What happens to the pressure inside of the container ?

• increases

• decreases

• stays the same

If the pressure and the amount of gas are held constant,

as the temperature of an enclosed gas increases, the volume

• increases

• stays the same

• decreases

Which factor can affect gas pressure?

• Temperature

• Volume

• Amount of Gas

• All of the answers are correct

• are unaffected
• move more quickly
• move more slowly
• stop moving

What is true of molecules of gas that are exposed to heat in a fixed volume container?

• They move faster and they cause the pressure to increase

• They move slower and pressure will decrease

• The volume increases and pressure increases

• The volume decreases and the pressure decreases.

This is an example of.....

• Gas
• Liquid
• Solid

Which of the following explains the change in pressure when volume increases?

• As the volume increases, the particles slow down, causing less collisions and less pressure.
• As the volume increases, the particles speed up, causing more collisions and more pressure.
• As the volume increases, the particles have more space to move and collide less with the walls , causing pressure to decrease.
• As the volume increases, the particles have more space to move and collide less with the walls , causing pressure to increase.

Which of the following describes why the pressure of a gas in a metal tank increases when temperature increases?

• As temperature increases, the particles have more space to move and collide less often with the container.

• As temperature increases, the particles have less space to move and collide more often with the container.

• As temperature increases, the particles slow down and collide less often with the container.

• As temperature increases, the particles speed up and collide more often with the container.
