1.	A heat engine converts heat energy from fuel combustion or any other source into which type of work?(a) Electrical work(b) Mechanical work(c) Pressure work(d) None of the mentionedI have been asked this question in an internship interview.I'm obligated to ask this question of Heat Engines in chapter Internal Combustion Engines of Automobile Engineering
Answer» The correct choice is (b) Mechanical work To ELABORATE: A heat engine GIVES mechanical work as output. In a heat engine, input is GIVEN in the FORM of heat and this heat is converted into mechanical work. The remaining heat which is not converted into work is EXHAUSTED.
