According to Newton’s law of cooling, the rate of cooling of a body is proportional to (Deltatheta)^(n) , where Deltatheta is the difference of the temperature of the body and the surrounding, and n is equal to :

Ac cording to Newton's law of cooling, the rate of cooling of a body is proportional to (Delta theta)^(n) , where Delta theta is the difference of the temperature of the body and thae surrounding. What is the value of n out of 4,3,2,and 1?

According to ‘Newton’s Law of cooling’, the rate of cooling of a body is proportional to the

As difference of temperature of body and surroundings increases, rate of cooling

Newton’s law of cooling says that the rate of cooling of a body is proportional to the temperature difference between the body and its surrounding when the difference in temperature is small. (a) Will it be reasonable to assume that the rate of heating of a body is proportional to temperature difference between the surrounding and the body (for small difference in temperature) when the body is placed in a surrounding having higher temperature than the body? (b) Assuming that our assumption made in (a) is correct estimate the time required for a cup of cold coffee to gain temperature from 10^(@)C to 15^(@)C when it is kept in a room having temperature 25^(@)C . It was observed that the temperature of the cup increases from 5^(@)C to 10^(@)C in 4 min

Assertion: According to Newton's law of cooling, the rate of loss of heat, -dQ//dt of the body is directly proportional to the difference of temperature. Reason :This law holds for all type of temperature differences.
