Describe what happens when two substances at different temperatures come into contact. Describe how the law of conservation of energy applies to this system. Give an example of where this could occur in your everyday life. Is your example an endothermic or exothermic reaction? How do you know?

Explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
