Q. A cane is taken out from a refrigerator at 0$℃$. The atmospheric temperature is 25$℃$. If $t_{1}$ is the time taken to heat from 0$℃$ to 5$℃$ and $t_{2}$ is the time taken from 10$℃$ to 15$℃$, then
A) $t_{1} > t_{2}$
B) $t_{1} < t_{2}$
C) $t_{1} = t_{2}$
D) There is no relation
Explanation
(b) According to Newton’s law of cooling $t_{1}$ will be less than $t_{2}$.
