The correct answers are:
The temperature of milk falls off exponentially with time
,
While cooling, there is a flow of heat from milk to the surrounding as well as from surrounding to the milk but the net flow of heat is from milk to the surrounding and that is why it cools
,
All three phenomenon, conduction, convection and radiation are responsible for the loss of heat from milk to the surroundings

When hot milk spread on the table heat is transferred to the surroundings by conduction, convection and radiation.
By Newton's law of cooling the heat temperature of the milk falls off exponentially while cooling very small amount of heat also will be transferred from surroundings to the milk but will be lesser than that of transferred from milk to the surroundings.
