For many purposes, we can treat methane (CH4) as an ideal gas at temperatures above its boiling point of -161 C.

Suppose the temperature of a sample of methane gas is lowered from -44.0C to -67.0C, and at the same time the pressure is decreased by 15.0%

Does the volume of the sample increase, decrease, or stay the same?

If you said the volume increases or decreases, calculate the percentage change in the volume. Round your answer to the nearest percent.
