Hello!

Here is your answer!
==========================================================

Simple definition of Endothermic and Exothermic:

Exothermic reactions are those which liberate heat during the reaction thus rising the temperature of the surrounding 
while 
endothermic are those which absorb heat from the surrounding for the reaction to take place and thus decreasing the temperature of surrounding

Difference Between Endothermic (@) and Exothermic Reactions ($)
@A reaction that the system absorbs energy from its surrounding in the form of heat
$.A reaction that releases energy from the system in the form of heat.
@The energy is absorbed from the surround into the reaction.
$The energy is released from the system to its environment.
@Energy in the form of heat.
$Energy is released as heat, electricity, light or sound.
@Melting ice, evaporation, cooking, gas molecules, photosynthesis are few examples.
$Rusting iron, settling, chemical bonds, explosions, nuclear fission are few examples.

Hope it helps!

Hey there !!

★What is Exothermic Reaction in simple word ? -
It is the reaction where heat is evolve during reaction between 2 or more substances

In other word ,


The reactions which are accompanied by the evolution of heat , are called exothermic reaction ( Combustion reaction)

★Fact to know -
Respiration is an exothermic process the decomposition of vegetable matter into copost is also an Example of an exothermic reaction

Ex - CH4. + 2O2 -->CO2 + 2H20 + ∆ and water


Endothermic Reaction -

It is the reaction where head is absorbed

in other word
The reactions which occur by the absorption of heat/energy are called endothermic reactions , it is also called hypothermic reaction

Fact -
As a result of this , the extra energy is absorbed in the forms of heat photosynthesis is an endothermic process

Ex - 2HgO + Heat ( ∆) --> 2Hg + O2

Hope this helps u!!!
