What is the approximate theoretical maximum efficiency of a heat engine receiving heat at 627°c and rejecting heat to 27°c? a)-23.2 b)-0.96 c)-0.04 d)-0.33 e)-0.66

The correct option is  (e) η = 0.66

Explanation:

given data:

temperature at entry is 627 degree C

temperature at exit is 27 degree C

the efficiency of a engine is given as η

where is temperature in kelvin at exit point

          is temperature in kelvin at entry point

η = 66.66 %

answer:

truck

explanation:

its a truck maybe cause a rv is like a truck and yea but plz mark brainlest!
