A glass full of hot milk is poured in the table. It begins to cool gradually.
Which of the following is incorrect?

Options

A. The rate of cooling is constant till milk attains the temperature of the surrounding
B. The temperatue of milk falls off exponentially with time
C. While cooling there is a flow of heat from milk to surrounding as well as from surrounding to the milk but net flow of heat is from milk to the surrounding and that is why it cools
D. All three phenomenon, conduction, convection and radiation are responsible for the loss of heat from milk to the surroundings

Answer

B, C, D

Explanation

When hot milk spread on the table heat is transferred radiation Because the surface area of poured milk on a table is more than the surface area of milk filled in glass Hnece, its temperature falls of exponentially according to Newton's law of cooling .
