Answer

B

Answer

Explanation:

The given question is related to the behavior of a body partially submerged in a liquid.

List-I
a. Lubrication
b. Rise of sap in trees
c. Formation of droplets
d. Cavitation

List-II
1. Capillary
2. Vapor pressure
3. Viscosity
4. Surface tension

Let's understand the behavior of a body partially submerged in a liquid and its relation with each option in List-I.

Lubrication:
Lubrication refers to the process of reducing friction and wear by introducing a lubricant between two surfaces in relative motion. It helps in reducing the resistance and improving the efficiency of the system. However, the lubrication process is not directly related to a body partially submerged in a liquid. Therefore, option 'a' is not related to any option in List-II.

Rise of sap in trees:
The rise of sap in trees is the process by which water and dissolved minerals are transported from the roots to the leaves. This process is mainly facilitated by capillary action. Capillary action is the ability of a liquid to flow in narrow spaces or tubes, against the force of gravity. Therefore, option 'b' is related to option '1' in List-II.

Formation of droplets:
The formation of droplets occurs when a liquid accumulates into small spherical shapes due to surface tension. Surface tension is the property of a liquid that allows it to resist an external force and minimize its surface area. Therefore, option 'c' is related to option '4' in List-II.

Cavitation:
Cavitation is the formation of vapor-filled cavities or bubbles in a liquid, usually caused by rapid changes in pressure. These cavities collapse or implode when the pressure is restored. Cavitation can cause damage to equipment and reduce its efficiency. Vapor pressure is the pressure exerted by the vapor of a substance in equilibrium with its liquid phase at a given temperature. Therefore, option 'd' is related to option '2' in List-II.

Conclusion:
Based on the above analysis, the correct matching between List-I and List-II is as follows:

a. Lubrication - (Not related to any option in List-II)
b. Rise of sap in trees - Capillary (Option 1)
c. Formation of droplets - Surface tension (Option 4)
d. Cavitation - Vapor pressure (Option 2)

Therefore, the correct answer is option 'A' (3 1 4 2).
