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

a. conduction

b. convection

c. thermal radiation

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.

Conduction, i'm doing the same question xd
