Question

Which physical quality does Not charge during the free of ideal gas? Pressure volume temperature Which definition of efficiency of heat engine is valid for any heat engine? Cannot engine working between 100 Degree C and 200 Degree C has efficiency e-2 e - 0.21 e - 0.27 Which statement about the coefficient of performance of a refrigerator K is current? K 1 All values listen in A, B and C Possible The cycle represented in this T(S) diagram is called Otto cycle Diesel cycle Carnot cycle Calculate efficiency of this engine Calculate total heat delivered in this cycle Two processes are scheduled on the figure below. Which process is reversible? Work done in a cycle is the measure of performance of engines. Heat engine with which cycle graphed on PV diagram has larger efficiency? Cycle because the work in this cycle is larger cycle Which formulation of the 2nd law of thermodynamics is incorrect? It is impossible to transfer heat from cold to hot body without doing work. engine We cannot use all heat from hot reservoir use it entirely for work. than Carnot All engines working between temperatures have efficiencies lower real certain Entropy always increases.

Explanation / Answer

1] option C is correct.

Since it is expansion, both volume and entropy change. Pressure also drecreases to zero.

But temperature remain same.
