1 Answer

Answer :

(4) prevent the heat of the body from escaping Explanation: It is just because woolen clothes have fibres and between those fibres air is trapped which reduces heat loss. Air reduces heat loss because it is an insulator or poor conductor of heat. Hence, all the heat from our body gets trapped inside the clothes which makes us feels warmer with the clothes.

Why do wet clothes dry faster in winter than rainy days ?

Description : Why do wet clothes dry faster in winter than rainy days ?

Last Answer : On a rainy day the atmosphere is saturated with water vapor. As a result, air cannot hold large amounts of water vapor. Winter air is dry. The air is waterless. This air wants to be saturated by absorbing water vapor quickly from the wet. As a result, wet clothes dry quickly in winter.
