A gas inside of a test chamber has 35 J of heat removed from it as the sample is compressed by a device that does 50 J of work on it. What is the change in the thermal energy of the gas? Does the temperature of the gas increase or decrease? If the gas expands, doing 50J of work on the compressing device, does the temperature of the gas increase or decrease?
