We have a container of 1.89 moles of an ideal monatomic gas. The volume of the container is 15.0 liters, and the temperatureof the gas is 21.7 degrees C. We compress the gas adiabatically to 13.6 liters. (a) Find the final temperature (K) of the gas. Neglect any heat flow into the surroundings. Caution: Be sure to use the ideal value for y, not the approximate value. (b) Find the change in internal energy (J) of the gas. (c) Find the work done (J) on the gas. Be sure to include the correct signs on the answers.
