Q197 / 200 · Manipal (MET) 2010 · Physics

When a number of small droplets combines to form a large drop, then

A
energy is absorbed
Correct answer
B
energy is liberated
C
energy is neither liberated nor absorbed
D
process is independent of energy

Solution

When a number of small droplets coalesce to form a bigger drop surface energy is released because its surface area decreases.

Hence, the correct answer is option: 'B'.
