Answer:
Q = h . A . (T (t) - T env)
the rate of loss of heat from a body is directly proportional to the difference in the temperature of the body and its surroundings.
Step-by-step explanation:
Q = rate of heat transfered out of the body
h = heat transfers coefficient
A = heat transfer to surface area
T = temperature of the objects surface
T env = temperature of the environment
T (t) = time dependent temperature
