endo thermic reactions absorb heat from the surroundings. examples would be air conditioners, refrigerators, and ice packs.
Any everyday problem that involves excess heat are open to the application of an endothermic reaction.
melting ice is an endothermic reaction. The ice absorbs heat from the surrounding environment to break the hydrogen bonds in the water molecules. The loss of heat energy is balance by the increase in entropy.
When you put ice in your coke this is an application of an endothermic reaction.
The refrigerator uses a liquid that absorbs heat turning the liquid to gas. This is an endothermic reaction that keeps your refrigerator cold and your milk from going sour.
( There has to be an exothermic reaction to balance the refrigerator. In the back of the refrigerator there is a condenser that turns the gas back into a liquid. This reaction requires energy be put into the reaction and releases heat into the environment. )
