1. Calculate the work and heat exchange with the surroundings of 1mol monatomic ideal gas in a reversible (a) isothermal, (b) adiabatic, and (c) isobaric expansion from volume V0 to 2V0. Give your results as a function of initial and/or final temperatures. For both the isothermal and isobaric expansions, calculate the efficiency, defined as the ratio of the work done by the system to the heat that it absorbs from the surroundings
