Is the rate of cooling the same thing as the rate of loss of heat? Explain.

The rate of cooling of a body is .

Two bodies have thermal capacities in the ration 3:4 and the rates of loss of heat in the ratio "3:5" .Their rates of cooling will be in the ratio of

The bodies have thermal capacities in the ratio 3:4 and the rates of loss of heat in the ratio 3:5 Their rates of cooling will be in the ratio of .

Derive Newton's law of cooling to show that the rate of loss of heat from the body is proportional to the temperature difference between the body and its surroundings.

Is the rate of heat production always the same

What is the difference between rate of cooling and rate of loss of heat?
