Are rate of heat emission and rate of cooling same ? Explain this.

A cup of tea cools from $65.5^o C to 62.5 ^o C$ in one minute in a room of $22.5 ^o C$. How long will the same cup of tea take, in………….. minutes, to cool from $46.50^o C to 40.5 ^o C$ in the same room ? (choose nearest value)

$Assertion :$ A tube light emits white light.
$Reason :$ Emission of light in a tube takes place at a very high temperature.

The temperature of a liquid drops from $365K$ to $361 K$ in $2$ minutes. Find the time during which temperature of the liquid drops from $344\;K$ to $342K$. Temperature of room is $293\;K$  ……. $\sec$

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 $69\,^{\circ} C ?$
