Describe the procedure to demonstrate that the rate of loss of heat from a hot body is directly dependent on the temperature difference between the body and its surroundings.

(N/A) $1$. Take approximately $300 \ ml$ of water in a calorimeter equipped with a stirrer and cover it with a lid having two holes.
$2$. Insert a thermometer through one hole in the lid,ensuring the bulb is fully immersed in the water. Record the initial reading,$T_{1}$,which represents the temperature of the surroundings.
$3$. Heat the water in the calorimeter until it reaches a temperature approximately $40^{\circ} C$ above the room temperature (surroundings temperature).
$4$. Remove the heat source to stop heating the water.
$5$. Start a stopwatch and record the temperature of the water at fixed intervals (e.g.,every one minute) while stirring gently.
$6$. Continue recording the temperature $(T_{2})$ until the water cools down to about $5^{\circ} C$ above the surroundings temperature.
$7$. Plot a graph with the temperature difference $\Delta T = T_{2} - T_{1}$ on the $y$-axis and the corresponding time $t$ on the $x$-axis.
$8$. From the graph,you will observe that the cooling rate is initially high and decreases as the body's temperature approaches the surroundings temperature. This confirms that the rate of heat loss depends on the temperature difference between the body and its surroundings.
