Answer 1

Exothermic:
-making ice cubes
-formation of snow in clouds
-rusting iron
-burning sugar

Endothermic:
-melting ice cubes
-evaporation of water
-cooking an egg

Another simple example of an exothermic reaction is combustion, such as lighting a candle. An initial input of energy causes oxygen and wax react to produce carbon dioxide, water, and heat.
