    One mole of an ideal, monoatomic gas undergoes the following processes:

    - Reversible, isothermal expansion from 10 atm to 2L and 5 atm ;
    - Adiabatic expansion from 10 atm to 2L and 5 atm ;

    Calculate q , w , change in U, and change in H for each process.

    State functions and heat capacities for ideal gases
    One mole of an ideal, monoatomic gas undergoes the following processes:
    For reversible isothermal expansion of an ideal gas,
    ΔU = 0 and ΔH = 0

    Work done, w = nRT ln (P1/P2)
    = - (1 mol) (8.314 J K-1 mol-1) (298 K) ln (10 atm / 5 atm)
    temp should be provided instead of ...
