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 ...
