Question

Two droplets coalesce in single drop in this process
a) energy is liberated
b) ebergy is absorbed
c) energy does not change
d) some mass is converted into energy

Pls explain it !

Answer 1

Answer:

Energy is liberated in this process

Explanation:

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

Hope it helped you.

Answer 2

The energy is liberated when two droplets coalesce in single drop

Explanation:

When two droplets coalesce in single drop,

• The surface area of is decreased for the single drop formed when compared with two individual droplets.
• It is understood that the process of coalesce decrease the surface area.
• We know that the surface area and surface tension are related with each other.
• The decrease in area results in decrease in surface area energy and also decrease in surface tension energy.
• So there is a variation in energy, also the energy present before the coalesce is greater than the energy after coalesce.
• Therefore , the process of coalesce results in liberation of energy, when two droplets coalesce in single drop.
