A heat engine containing 2.50 L of an ideal monoatomic gas at 310.15 K, 1.00 atm (Cp,m = 5/2 R) is designed to go through the following cycle: %3D AB; A 2-fold decrease in pressure under constant volume conditions. B>C; Isothermal expansion to increase the volume by 4-fold. C→D; Reversible adiabatic compression to the initial pressure. D→A; Constant pressure compression back to the initial volume. What is the entropy change for the surroundings for the first step in the cycle if the temperature of the surroundings is -50.0 °C?
