Question

Explain endothermic and exothermic reactions

Answer 1

$\boxed{\boxed{\sf Endothermic \ reaction }}$

• It is the type of reaction in which heat energy is Absorb

• It absorbs the heat and make the surrounding cool

• Melting ice cubes , Evaporation

• Its general form is Reactant + heat ---) Product

$\boxed{\boxed{\sf Exothermic \ reaction}}$

• It is the type of reaction in which heat energy is releases

• It releases the heat and make the surrounding warm

• for ex - Respiration , Digestion

• Its general form is Reactant ---) Product + heat

MORE TO KNOW

• All decomposition reaction are endothermic reaction as decomposition reaction needs energy in the form of heat , light or electricity to break down its reactants.
