Question

Two water droplets combine to form a large drop in this process energy is

Answer 1

Answer:

Two individual liquid drops have a greater surface area than that of a single drop formed after their coalescence. ... Since final energy(after coalescence) is less than the initial energy, energy must be released in the process. Therefore, coalescence of drops releases energy and splitting up a drop requires energy.

Answer 2

Releases Energy

Explanation:

• When two water droplets combine to form a large drop the surface area decreases after its combination
• Surface area of two droplet is greater than the large single droplet due to which the surface tension is reduced
• Due to decrease in surface tension its energy is also decreased.
• As the energy is reduced it releases energy

∴ We can conclude that when two water droplets combine to form a large droplet it releases energy.
