MCQ
In Carnot engine the work done by working substance is equivalent to
  • A
    Heat taken by source
  • B
    Heat given to sink
  • ✓
    Difference between heat taken by source and heat given to sink
  • D
    ratio of heat taken and heat given
✓

Answer

Correct option: C.
Difference between heat taken by source and heat given to sink
c
It's a cyilic process

Hence, $Q\ =\ w\ [As\ \Delta u =\ 0]$
