Question

find the effeciency of heat engine working between 27°C and 927°C​

Answer 1

Answer:

• To calculate efficiency the formula that is used is

efficiency = 1 - T2 / T1

according to the question,

T1 = 327 degree Celsius = 327+ 273 = 600K

T2 = 27 degree Celsius = 27 + 273 = 300k

now, Efficiency is equal to,

E = 1 - 300/600

E = (600 - 300 ) / 600

E = 300 / 600

E = 1/2 joules

E = 0.5 joules
