Statement II: Excess pressure inside a drop is directly proportional to its surface area.

A

Statement I is true, statement II is true and Statement II is a correct explanation for Statement I.

B

Statement I is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
C
From the formula,
Express pressure `= 2T//r`,
Here, `T` is surface tension, `r` is the radius of liquid drop. Hence, excess pressure is inversely proportional to radius and hence the surface, area. Therefore, the excess pressure inside a smaller drop is larger as compared to the larger drop due to which smaller drop of liquid resists deforming forces better than a larger drop.

Derive an expression for excess pressure inside a drop of liquid.

Small droplets of liquid are usually more spherical in shape than larger drops of the same liquid because

Small droplets of a liquid are usually more spherical in shape than larger drops of the same liquid because

Statement-1: Two identical conincal pipes shown in figure have a drop of water. The water drop tens to move towards tapered end. Statement-2: Excess pressure is directed towards centre of curvature and inversely proportional to radius of curvature. Net excess pressure is therefore, directed towards tapered end. So the water drop tends to move towards tapered end.

Statement I: Droplets of liquid are usually more spherical in shape than large drops of the same liquid. Statement II: Force of surface tension predominates force of gravity in case of small drops.
