Which of the following is
NOT a feature of Carnot engine?
It has the maximum
efficiency among all the engines.
The efficiency of Carnot engine is dependent
on temperatures.
It works with only one heat reservoir.
For all Carnot engines,
working under same temperature range has same efficiency.
It works with only one heat reservoir.
The Kelvin-Planck’s statement of the second law tells
that it is impossible to construct a PMMSK,
which receives energy as heat from a single thermal reservoir and delivers as
equivalent amount of work.
Hence,
the correct option is (C).
