A reversible engine converts one-sixth of the heat input into work. When the temperature of the sink is reduced by 62∘C, the efficiency of the engine is doubled. The temperatures of the source and sink are A reversible engine converts one-sixth of the heat input into work. When the temperature of the sink is reduced [...]

A Carnot’s engine operates with a source at 500 K and sink at 375 K. The engine consumes 600 kcal of heat in one cycle, the heat rejected to the sink per cycle is A Carnot's engine operates with a source at 500 K and sink at 375 K. The engine consumes 600 kcal of [...]

The temperature T1 and T2 of two heat reservoirs in an ideal Carnot engine are 1500°C and 500°C respectively. If T1 increases by 100°C what will be the efficiency of the engine? The temperature T1 and T2 of two heat reservoirs in an ideal Carnot engine are 1500°C and 500°C respectively. If T1 increases by [...]

An ideal gas at pressure P is adiabatically compressed so that its density becomes n times the initial value. The final pressure of the gas will be (γ=CP/CV) An ideal gas at pressure P is adiabatically compressed so that its density becomes n times the initial value. The final pressure of the gas will be [...]

A quantity of a substance in a closed system is made to undergo a reversible process from an initial volume of 3 m^(3) and initial pressure 10^(5) N/m^(2) to a final volume of 5m^(3). If the pressure is proportional to the square of the volume (i.e,P=AV^(2)), the work done by the substance will be Heat [...]
