n moles of a diatomic ideal gas go through cycle a → b → c → d → a as shown in the figure. Processes ab and cd are isothermal and occur at temperatures TH and TC, respectively.   1) Calculate the work Wab done by the gas during the process a → b in terms of the variables in the problem.  2) Calculate the work Wbc done by the gas during the process b → c.  3) Calculate the total work W done in the entire cycle in terms of the variables in the problem.  4) Calculate the total heat Q flowing into the gas in a complete cycle.

Consider a process that uses n moles of a monatomic ideal gas operating through a Carnot cycle. The initial temperature and pressure of the gas are T1 and P1, respectively. Consider steps 1 → 2, 2 → 3, 3 → 4, and 4 → 1. In the adiabatic heating, the temperature of the gas is doubled. Write an expression for the volume V3 after this step in terms of V1.  Write an expression for P3 in terms of n, R, T3 and V3.

A Carnot engine operates with an efficiency of 30%. The temperature of the cold reservoir remains at 10°C. a. Calculate the temperature of the hot reservoir. TH = %3D b. By how much does the temperature in the hot reservoir need to be raised so that the efficiency of the engine becomes 50%. Express your answer in degrees Celsius.

The heat of melting of ice at 1 atmosphere pressure and 0°C is 1.4363 kcal/mol. The volume of ice is 0.0196 liter and the volume of water is 0.018 liter. If 1 mole of ice is melted under these conditions, what will be a. The work done in cal? b. The change in internal energy in cal? c. The change in entropy in cal? Note Note that 1 literxatmosphere is equal to 101.325 joule. Sol": given Heat of melting ice at 1 atm pressure = 1.4363 kca kcal/ 2 = 1.4363 kcal/mole mole volume of ice = 0·0196 lts " water = 0.018 lts @ work done is define as w=pdv » w = P(V₁ hot W = 1 (0·018-00196) W = 0·0016 Cal Pay Kat Ans
