Answer

A is the process which changes solid into liquid 

Therefore A = Melting/Fusion

 

B is the process which changes liquid into gas

Therefore B = Boiling/Vapourisation

 

C is the process which changes gas into liquid

Therefore C = Condensation

 

D is the process which changes liquid into solid

Therefore D = Freezing

 

E is the process which changes solid into gas, directly without coming in liquid state

Therefore E = Sublimation 

 

F is the process which changes gas into solid, directly without coming in liquid state

Therefore F = Sublimation
