Question

A down jacket keeps your body warm mostly by reducing which form of heat transfer?

a. conduction
b. convection
c. thermal radiation

Answer 1

conduction, i'm doing the same question xd

Answer 2

The correct answer is

a. conduction

In fact, conduction is the transfer of heat by contact between two mediums. The body exchanges heat by conduction with the air around it: when the down jacket is put on the body, it prevents heat from being given by the body to the surrounding air, therefore keeping the body warm.
