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?
