The efficiency of a Carnot engine which operates between the two temperatures ( T₁=500 ~K ) and ( T₂=300 ~K ) is

Options

  1. A( 50 % )
  2. B1) ( 25 % )
  3. C( 75 % )
  4. D( 40 % )

Correct answer

D. ( 40 % )

Step-by-step solution

Efficiency, ( = (1- T₂ T₁ ) 100 % ) Given ( T₁=500 ; T₂=300 ~K ) Therefore, ( = (1- 300 500 ) 100= 200 500 100=40 % )
