Woollen cloth protects the body from cold because – (1) it is a good conductor of heat (2) it is a poor conductor of heat (3) external heat rays enter into the body through the woollen cloth (4) it reflects heat

Description : Woollen cloth protects the body from cold because – (1) it is a good conductor of heat (2) it is a poor conductor of heat (3) external heat rays enter into the body through the woollen cloth (4) it reflects heat

Last Answer : (2) it is a poor conductor of heat Explanation: It is just because woolen clothes have fibres and between those fibres air is trapped which reduces heat loss. It reduces heat loss because it is an insulator or poor conductor of heat.
