When a drop of liquid splits up into number of drops (under isothermal conditions) 

a) Volume increase 

b) Total area increase 

c) Energy is absorbed 

d)  Energy is liberated 

 

• Volume remain same.
• The surface area of the liquid increases when a drop of liquid is sprayed into a lot of droplets. 
• The molecules from the liquid's interior ascend to the surface of the drops during this process, working against the cohesive force. 
• Area increases when a liquid drop divides into several drops. Energy is absorbed since it is needed to increase the surface area.

Hence the correct answer is b, c are correct.
