Three moles of an ideal monatomic gas expand at a constant pressure of 2.70 ; the volume of the gas changes from 3.40×10?2 to 4.60×10?2 . First calculate the initial temperature of the gas. Second calculate the final temperature of the gas. Thrid calculate the amount of work the gas does in expanding. Fourth calculate the amount of heat added to the gas. Then calculate the change in internal energy of the gas.
