    0.110 moles of a mono atomic gas follows the process shown in the figure

    Part A
    How much heat energy is transferred to or from the gas during process 1 to 2?

    Part B
    How much heat energy is transferred to or from the gas during process 2 to 3?

    Part C
    What is the total change in thermal energy of the gas?

    I can't figure this problem out. Below are some numbers that I have tired but were not right. I have an example of the same sort of problem except it has .190 moles. The answers to a was 810 J, and the answer to b was -486 J, part c has not been figured out yet. I know that it has something to do with the PV=nrt, and p has to equal to ka, not atm.

    Solution Summary

    The thermodynamic process is shown on a Pressure-Volume diagram, the heat transfered and the change in internal energy is calculated.
