Question

Newton's law of cooling states that the rate of cooling of a body is proportional to the _____________

Answer 1

Newton's law of cooling:

1. It states that the rate at which a body loses heat is directly proportional to the temperature difference between the body and its surroundings.
2. Mathematically, Newton's law of cooling is given by
   $\frac{-dQ}{dt}=\left(T-T_o\right)$,
3. where $\frac{dQ}{dt}$is the rate of loss of heat of the body, $T$ is the temperature of the body, and $T_o$ is the temperature of the surroundings.

Hence, Newton's law of cooling states that the rate of cooling the other of body is proportional to the temperature difference between the body and its surroundings.
