3.6 Exercise 33

One mole of an ideal gas is initially in a chamber of volume $1.0 \times 10^{−2} \left( \text{m}\right)^{3}$ and at a temperature of $27 ° \text{C}$. (a) How much heat is absorbed by the gas when it slowly expands isothermally to twice its initial volume? (b) Suppose the gas is slowly transformed to the same final state by first decreasing the pressure at constant volume and then expanding it isobarically. What is the heat transferred for this case? (c) Calculate the heat transferred when the gas is transformed quasi-statically to the same final state by expanding it isobarically, then decreasing its pressure at constant volume.
