Apparatus for Newton's Cooling Law Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12405
Jlab Export is a leading Apparatus for Newton's Cooling Law Manufacturer,and suppliers in India
Apparatus for Newton’s Cooling Law (code EL-PL-12405) is a cooling-curve apparatus with two copper calorimeters resting in a trough inside an outer tank, closed by a wooden top that has a hole for a thermometer over each calorimeter. Students use it to show that a hot body loses heat faster the further its temperature is above its surroundings. JLab makes this apparatus at its Ambala workshop in India.

What the Cooling Law Predicts
For a modest temperature excess, the rate at which a body loses heat is proportional to the difference between its temperature and that of its surroundings. A graph of temperature against time therefore falls steeply at first and flattens as the water approaches room temperature. Plotting the natural logarithm of the temperature excess against time gives a straight line, and its gradient gives the cooling constant.
Running the Experiment with Two Calorimeters
Fill one calorimeter with hot water, fit a thermometer through its hole in the wooden top and read the temperature at regular intervals as it cools. Keep the apparatus away from draughts and direct sun, because the law assumes the surroundings stay at one temperature. The second calorimeter allows a side-by-side comparison: equal volumes of water and another liquid cooled through the same temperature range lose heat at the same rate at each temperature, so, with the masses and the heat capacity of the calorimeter known, their cooling times give the specific heat capacity of the liquid by the method of cooling.
