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.

An engine operates in a Carnot cycle. At point A in the cycle, 2.34 mol of a monatomic ideal gas has a pressure of 1,400 kPa, a volume of 10.0 L, and a temperature of 720 K. The gas expands isothermally to point B and then expands adiabatically to point C, where its volume is 24.0 L. An isothermal compression brings it to point D, where its volume is 15.0 L. An adiabatic process returns the gas to point A....

In an engine cycle like the one shown in Figure
In an engine cycle like the one shown in Figure    heat is added over a range of temperatures. Explain why even if it were run reversibly, its efficiency would be less than the Carnot limit defined by the high- and low-temperature set points and shown in the figure ( ηC = T4-T2)/T4. Is this in itself a disadvantage of such a cycle?

A Carnot cycle uses 1.00 mol of a monoatomic perfect gas as the working substance from an initial state of 10.0 atm and 600 K. It expands isothermally to a pressure of 1.00 atm (step 1), and then adiabatically to a temperature of 300 K, (step 2). This expansion is followed by an isothermal compression (step 3), and then an adiabatic compression (step 4) back to the initial state. Determine the values of q, w, ÄU, ÄH, ÄS, and ÄSsurr...
