For many purposes we can treat propane

c3h8 as an ideal gas at temperatures above its boiling point of

−42.°c suppose the temperature of a sample of propane gas is raised from

27.0°c to 42.0°c, and at the same time the pressure is decreased by

5.0%

does the volume of the sample increase, decrease, or stay the same? increase
decrease
stays the same
if you said the volume increases or decreases, calculate the percentage change in the volume. round your answer to the nearest percent.
