Question

A substance cools from $75^{\circ} C$ to $100^{\circ} C$ in $T_{1}$ minute, from $70^{\circ} C$ to $65^{\circ} C$ in $T_{2}$ minute and from $65^{\circ} C$ to $60^{\circ} C$ in $T_{3}$ minute, then

T_{1} = T_{2} = T_{3}

Solution

The correct option is B $T_{1} < T_{2} < T_{3}$
When material's temperature is much more, it tends to cool faster therefore, $T_{1} < T_{2} < T_{3}$ .
