For many purposes we can treat propane (CH4) as an ideal gas at temperatures above its boiling point of -161. C. Suppose the temperature of a sample of propane gas is raised from -13.0 °C to 26.0 °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? If you said the volume increases or decreases, calculate the percentage change in the volume. Round your answer to nearest percent.
