Question

Explain heat exchange​

Answer 1

Answer:

The heat exchange between two objects is proportional to the difference of their temperatures. For the process of heat loss, internal heat has to be transported from the various tissues and organs to the cooler body surface. Heat transfer from the body core to the shell is called internal heat transport.

Answer 2

Answer:

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact.
