What are the four variables used to describe gases? Include the possible units for each variable! Explain the effect of:

Adding or removing gas to a constant volume. What happens to the pressure? Is this a direct or indirect relationship?

Increasing or decreasing volume of a gas. What happens to the pressure? Is this a direct or indirect relationship?

Raising or lowering temperature. What happens to the pressure? Is this a direct or indirect relationship

Why are gases easy to compress?

If the temperature is constant, what change in volume would cause the pressure of an enclosed gas to increase by a factor of 4?

Assuming the temperature is held constant, how could you increase the pressure inside a container by a factor of 3?

Explain why heating a contained gas that is held at a constant volume increases its pressure.

If a gas is compressed from 4L to 1L, and the temperature remains constant, what happens to the pressure?
