A rigid tank of small mass contains $40.0 \mathrm{g}$ of argon, initially at $200^{\circ} \mathrm{C}$ and $100 \mathrm{kPa}$. The tank is placed into a reservoir at $0^{\circ} \mathrm{C}$ and allowed to cool to thermal equilibrium. (a) Calculate the volume of the tank. (b) Calculate the change in internal energy of the argon. (c) Calculate the energy transferred by heat. (d) Calculate the change in entropy of the argon. (e) Calculate the change in entropy of the constant-temperature bath.
