A heat engine is a device that uses to produce useful work.
The efficiency is defined as the work done by the engine divided by the heat supplied.
So, efficiency η = 1 - T₁/T₂
Where T₁ is the lower temperature and T₂ is the higher temperature.
The heat engine has efficiency depending on the factors - heat supplied and work done.
So, the heat engine is a device which uses heat to produce work.
Thus, the given statement is True.
