Question

"The rate of loss of heat $-dQ/dt$ of the body is directly proportional to the temperature difference $\Delta T = (T_2 - T_1)$ of the body and surroundings". This statement is

A

law of thermometry

B

Newtons law of cooling

C

law of calorimetry

D

zeroth law

Answer

Newtons law of cooling

Explanation

Solution

The rate of loss of heat of a body is represented as: $-\frac{ d Q}{ dt } \propto T _{2}- T _{1}$ This statement is Newton's law of cooling where the rate of loss of heat is directly proportional to the temperature difference between the body and the surroundings.
