Two droplets merge with each other and forms a large droplet. In this process
Correct answer: A. Energy is liberated
- A. Energy is liberated
- B. Energy is absorbed
- C. Neither liberated nor absorbed
- D. Some mass is converted into energy
Explanation
When two droplets merge, the resulting larger droplet has a smaller total surface area compared to the sum of the surfaces of the two individual droplets. Surface energy is proportional to surface area, so a decrease in surface area leads to a decrease in surface energy. This decrease in energy is liberated as the droplets merge. Therefore, option A is correct. Options B and C are incorrect as they fail to recognize the release of energy due to decreased surface area. Option D is incorrect as it improperly suggests mass-energy conversion, which is not applicable in this context.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
