Answer 1

Answer:-

a) Surface tension.

• It's surface tension which enables a cotton towel to soak water from our body.

• Surface tension is the property of the liquid by virtue of which the free surface of liquid at rest tends to have minimum surface area and as such it behaves as if covered with a stretched membrane.

Surface tension depends on two factors:-

1. Nature of liquid.
2. Temperature.

1. Surface tension is directly proportional to Nature of liquid .
2. Surface tension is inversely proportional to the temperature.

Answer 2

b capillarity is the correct answer about soaking water.

• The capillary action occurs due to presence of cohesive and adhesive force.
• Cohesive force is the force between water molecules and adhesive force is the force between water and the substance it is in.
• Capillary action is further due to the surface tension of water.
• The movement of water is due to greater adhesive force.
