Question

What other two examples of daily life situations can demonstrate the transformation of heat into mechanical energy?

Answer 1

Steam turbine and petrol engine.

Explanation:

Steam turbine does mechanical job of rotating the generator. This is mechanical work by using the heat energy from the steam.
Gas turbines make mechanical energy form the hot gases produced from combustion of petrol. Combustion of petrol produces heat energy (because the reaction is exothermic) and then it is converted into mechanical energy in the gas turbine.
