C2021 HW Part 1 + Isothermal Engine + Isothermal Engine Consider a thermal engine filled with N molecules of a monatomic ideal gas. The gas undergoes a cyclic transformation, as shown. (Figure 1) Processes AB and CD are isothermal (constant temperature), and processes BC and DA are isochoric (constant volume). The quantities P, P. V, and V are defined in the figure. For example, when the gas is in state A, it has pressure p and volume V; when the gas is in state B, it has volume V, but the pressure is not given.

Sun 3:32 PM q 1 previous 1 of 4 | next H Heat Finally, consider the heat absorbed by the gas during its cycle. Define Qs to be heat absorbed by the gas in process AB, etc. If a process is exothermic (e. heat is given off by the gas during the process), then the quantity of heat absorbed will be negative. Part H Indicate the processes in this cycle during which heat is flowing into the gas. That is, indicate the segments where is positive Hints
