MCQ
The efficiency of a Carnot engine depends upon
  • A
    the temperature of the source only
  • B
    the temperature of the sink only
  • the temperatures of the source and sink
  • D
    the volume of the cylinder of the engine

Answer

Correct option: C.
the temperatures of the source and sink
c
Efficiency of Carnot engine

$\eta=\left(1-\frac{T_{2}}{T_{1}}\right) \times 100 \%$

So efficiency depends on temperature of source $\left(T_{1}\right)$ and temperature of $\sin k\left(T_{2}\right)$
