Same thing is true of a steam engine. In a steam engine it is
the phase-change of the water that makes it possible to convert
the heat from burning fuel into mechanical energy.


Yes but the steam engine takes the high-energy water vapor and produces
mechanical energy while returning the water as a low energy liquid.
