For many purposes we can treat methane (CH) as an ideal gas at temperatures above its boiling point of - 161. °C. Suppose the temperature of a sample of methane gas is raised from 100.0 °C to 119.0 °C, and at the same time the pressure is decreased by 15.0%. increase Does the volume of the sample increase, decrease, or stay the same? decrease x 6 ? 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. 1%
