Condensation :-
- The process of changing of gaseous form to liquid form is called condensation.
- It requires evolution of heat.
- .Ex-water vapour➡️water.
Deposition :-
- the process of changing gases home directly into solid is called deposition ...
Give reasons :-
✨ when the temperature falls the intermolecular space decreases :-
Answer :-
➡️ When the temperature falls the intermolecular space decreases because the intermolecular forces become strong and kinetic energy decrease.
As the temperature decreases the kinetic energy cannot overcome intermolecular forces.
Hence, the matter become solid as temperature falls..
✨ water forms droplet :-
Answer :-
➡️ Water forms Droplets due to Cohesion ..
✨ Brownian motion is not observed in solids :-
Answer :-
➡️ The Brownian movement is due to the bombardment of the colloidal particles, by the molecules of dispersion medium which are in constant motion like molecules in gas..
