(a)
Interpretation:
Making popcorn in a microwave oven has to be classified as an endothermic or exothermic reaction.
Concept Introduction:
Exothermic reaction: Those reactions that release heat energy to the surroundings are called as exothermic reactions. The formation of
Endothermic reaction: Those reactions that absorb heat energy from the surroundings are called as endothermic reactions. The breakage of chemical bonds absorbs heat energy.

Interpretation:
A burning match has to be classified as an endothermic or exothermic reaction.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Boiling water has to be classified as an endothermic or exothermic reaction.
Concept Introduction:
Refer to part (a).
