Multiple choice general knowledge science & technology

All internal combustion engines depend on the----- chemical process of combustion:

  1. endothermic

  2. exothermic

  3. isothermic

  4. isobaric

B Correct answer
Explanation

Combustion is an exothermic chemical process - it releases heat energy. In internal combustion engines, this released energy creates pressure that drives pistons. Endothermic processes absorb heat, isothermic processes maintain constant temperature, and isobaric processes maintain constant pressure.
