Discuss the experiment verifying Newton's law of cooling.

Answer» <html><body><p></p>Solution :Newton.s law of cooling can be verified with the help of the experimental setup which consists of a double walled vessel (V) containing <a href="https://interviewquestions.tuteehub.com/tag/water-1449333" style="font-weight:bold;" target="_blank" title="Click to know more about WATER">WATER</a> in between the two walls. <br/> A copper calorimeter (<a href="https://interviewquestions.tuteehub.com/tag/c-7168" style="font-weight:bold;" target="_blank" title="Click to know more about C">C</a>) containing hot water is placed inside the double walled vessel. <br/> This calorimeter is <a href="https://interviewquestions.tuteehub.com/tag/closed-919469" style="font-weight:bold;" target="_blank" title="Click to know more about CLOSED">CLOSED</a> tightly by cock with two holes. <br/> Two thermometers through the corks are used to note the <a href="https://interviewquestions.tuteehub.com/tag/temperatures-1241229" style="font-weight:bold;" target="_blank" title="Click to know more about TEMPERATURES">TEMPERATURES</a> `T_(2)` of water in calorimeter and `T_(1)` of hot water in between the double walls respectively. <br/> 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 <a href="https://interviewquestions.tuteehub.com/tag/slope-15649" style="font-weight:bold;" target="_blank" title="Click to know more about SLOPE">SLOPE</a> <br/> It is like `log_(e)(T_(2)-T_(1))=-"Kt"+C` and It is similar to `y=-"mx"+C`</body></html>
