Vedclass · Answer

(C) Newton's law of cooling states that the rate of loss of heat of a body is directly proportional to the difference in temperature between the body and its surroundings,provided the difference is small.Mathematically,it is expressed as $\frac{dQ}{dt} = -k(T - T_0)$,where $T$ is the temperature of the body and $T_0$ is the temperature of the surroundings.Since $\frac{dQ}{dt} = mc \frac{dT}{dt}$,we can write $mc \frac{dT}{dt} = -k(T - T_0)$.By measuring the rate of cooling $\frac{dT}{dt}$ for a liquid of known mass $m$,the specific heat capacity $c$ of the liquid can be determined experimentally.Therefore,Newton's law of cooling is primarily used in the laboratory to determine the specific heat of liquids.
