A body takes $10$ minutes to cool down from $62^o C$ to $50^o C$. If the temperature of surrounding is $26^o C$ then in the next $10$ minutes temperature of the body will be ……… $^oC$

A pan filled with hot food cools from $94\,^{\circ} C$ to $86\,^{\circ} C$ in $2$ minutes when the room temperature is at $20\,^{\circ} C$. How long (in $sec$) will it take to cool from $71\,^{\circ} C$ to $69\,^{\circ} C ?$

Discuss the experiment verifying Newton's law of cooling.

Ice is used in a cooler in order to cool its contents. Which of the following will speed up the cooling process?

A body cools in $7$ minutes from $60^{\circ}\,C$ to $40^{\circ}\,C$. The temperature of the surrounding is $10^{\circ}\,C$. The temperature of the body after the next $7$ minutes will be
