Consider the ideal Stirling cycle shown above, working between a maximum temperature of 600 K and a minimum temperature of 370 K and a minimum volume of 0.3 L and a maximum volume of 1.6 L. The working gas of the cycle is 0.10 mol of an ideal gas with c′v = 20.8 J/mol-K. Note, +Q = heat absorbed by the gas and +W = work done by the gas. |

As shown in the pV diagram, an ideal gas moves through a cycle from A to B to C and then back to A. From state A to state B, the ideal gas absorbs 80.0 J of heat and its internal (i.e. its thermal) energy increases by 30.0 J. From state B to state C, the internal energy of the ideal gas decreases by 20.0 J. As such, determine the following quantities: B V The work done...
