LAB REPORT
Newton’s Law of Cooling for a Warm Object
Introduction
The cooling rate of an object is relative to the temperature distinction amongst it and its
environment.
The heat lost by an object to the environment can be computed as;
Q = mc△T = mc(T-T0) = mc(X-X0)
Where, Q is heat lost, m is mass of water, c is the specific heat capacity of water and △T
is the temperature change.
Objective
To determine the decay law by measuring the temperature of a container of cooling water
after being heat to a high temperature.
