For many purposes we can treat ammonia (NH) as an ideal gas at temperatures above its boiling point of – 33. °C. Suppose the temperature of a sample of ammonia gas is raised from 85.0 °C to 121.0 °C, and at the same time the pressure is

increased by 15.0%.

increase

Х

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

decrease

O stays the same

If you said the volume increases or decreases, calculate the percentage change in 0%

the volume. Round your answer to the nearest percent.
