Question

An ideal gas heat engine is operating between 227 ° C and 127 ° C . It absorbs 10 4 J of heat at the higher temperature. The amount of heat converted into work is, 2000 J, 4000 J, 8000 J, 5600 J

MARKS App · Accepted Answer

η = 1 - T 2 T 1 = 1 - 127 + 273 227 + 273 = 1 5 W = η Q 1 = 1 5 × 10 4 J = 2000 J
