A large number of water drops, each of radius 
, combine to have a drop of radius 
. If the surface tension is 
and mechanical equivalent of heat is 
, the rise in heat energy per unit volume will be:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
is the radius of bigger drop.
is the radius of 
water drops.
Water drops are combined to make bigger drop.
So,
Volume of 
drops 
volume of bigger drop
