Question

Consider the reversible Carnot cycle shown in the following figure given below with 1.19 mol of an ideal gas with C V,m =5R/2 as the working substance. The initial isothermal expansion occurs at the hot reservoir temperature of T hot = 890 K from an initial volume of 3.85 L ( V a ) to a volume of 10.5 L ( V b ) . The system then undergoes an adiabatic expansion until the temperature falls to T cold = 298 K . The system then undergoes an isothermal compression and a subsequent adiabatic compression until the initial state described by T a = 890 K and V a = 3.85 L is reached. Calculate Vc, Vd , wab,wbc,wcd,wda,wtotal for this step in the cycle. Calculate E . Calculate the amount of heat that is extracted from the hot reservoir to do 1.00 kJ of work in the surroundings.
