Can a Carnot engine be realised in practice ?

Can a perfect blackbody be realized in practice ?

What is Camot engine?

What is the efficiency of a Carnot engine working between ice point and stean point ?

A diatomic ideal gas is used in a Carnot engine as the working substance. If during the adiabatic expansion part of the cycle the volume of the gas increase from V to 32V, the efficiency of the engine is

Efficiency of a Carnot engine is 50% when temperature of outlet is 500 K . In order to increase efficiency up to 60% keeping temperature of intake the same what is temperature of outlet?

When the absolute temperature of the source of a Carnot heat engine is increased by 25 %, its efficiency increases by 80%. The new efficiency of the engine is

The efficiency of a Carnot engine which operates between the two temperatures T_1=500K and T_2=300K is

Two Carnot engines A and B are operated in series. A receives heat at 900 K and rejects it to the reservoir at TK. B receives the rejected heat from Aand rejectsit to itsreservoir at 400 K. If the work outputs of A and B are equal, then T is

Two Carnot engines A and B are operated in succession. The first one , A receives heat from a source at T_1 = 800 K and rejects to sink at T_2K . The second engine B receives heat rejected by the first engine and rejects to another sink at T_3 = 300K . If the work outputs of two engines are equal , them the value of T_2 is
