We start with 5.00 moles of an ideal monatomic gas with an initial temperature of 121 °C. The gas expands and, in the process, absorbs an amount of heat equal to 1240 J and does an amount of work equal to 2160 J.
Part A:
What is the final temperature Tfinal of the gas? Use R = 8.3145 J / (mol · K) for the ideal gas constant.
