For many purposes we can treat methane as an ideal gas at temperatures above its boiling point of . Suppose the temperature of a sample of methane gas is lowered from to , and at the same time the pressure is decreased by . 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.
