Question

which process is given as an example of an endothermic process? the combustion of fuel a moving car melting ice designing efficient engines

Explanation:

An endothermic process absorbs heat from the surroundings. Combustion of fuel releases heat (exothermic). A moving car involves energy conversion (not endothermic in the heat - absorption sense). Designing engines is an engineering task, not a thermodynamic process example. Melting ice absorbs heat from the environment to change from solid to liquid, so it's endothermic.

Answer:

Melting ice
