Question

define exorthermic and endothermic reaction?​

Answer 1

Answer:

• In an exothermic reaction, the heat is given out or released.
• In an endothermic reaction the heat is absorbed.

Answer 2

Answer:

ENDOTHERMIC REACTION:-

Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect. Physical processes can be endothermic as well – Ice cubes absorb heat energy from their surroundings and melt to form liquid water (no chemical bonds are broken or formed).

EXOTHERMIC REACTION:-

An Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light. These reactions are the opposite of endothermic reactions and can be expressed in a chemical equation as follows: Reactants → Products + Energy
