Discuss the experiment verifying Newton's law of cooling.

Explanation

Newton.s law of cooling can be verified with the help of the experimental setup which consists of a double walled vessel (V) containing water in between the two walls.
A copper calorimeter (C) containing hot water is placed inside the double walled vessel.
This calorimeter is closed tightly by cock with two holes.
Two thermometers through the corks are used to note the temperatures `T_(2)` of water in calorimeter and `T_(1)` of hot water in between the double walls respectively.
Temperature of hot water in the calorimeter is noted after equal intervals of time. A graph is plotted between `log_(e)(T_(2)-T_(1))` and time (t). The nature of the graph is observed to be a straight line having a negative slope
It is like `log_(e)(T_(2)-T_(1))=-"Kt"+C` and It is similar to `y=-"mx"+C`
