A bottle of mineral water at a room temperature of 72 is kept in a refrigerator where the temperature is 44 .After half an hour water cooled to 61 .What is the temperature of the body in another half an hour?(Take log ( frac{28}{17} ) = 0.498, e-0.99=0.37)
A body in air at 25 cools from 100 to 75 in 1 minute. What is the temperature of the body at the end of 3 minutes? (Take log(1.5)=0.4)
According to Newton s law of cooling The change of temperature of a body is proportional to the difference between the temperature of a body and that of the surrounding medium . If t1 is the initial temperature of the body and t2 is the constant temperature of the medium, T be the temperature of the body at any time t then find the expression for T as a function of t1 , t2 and time t.
