Carnot efficiency. The second law of thermodynamics puts a fundamental limit on the thermal efficiency of all heat engines. Even an ideal, frictionless engine can't convert anywhere near 100% of its input heat into work.

neenu9: but i mean wats the formula to find the efficency

where, Tl is the lower working temperature and Th is the higher working temperature.

As can be observed, for a carnot engine to have efficiency equal to 1, either Tl has to be absolute zero (not possible) or Th has to be infinite (not possible either).

Therefore, the efficiency of a carnot engine is always less than one but since it is a reversible engine, it can be proved that this value of efficiency is still the highest possible value between any two specified working temperatures.

hope this answer helpful u


neenu9: Thanku mate
