    Answer: (4). All of the above

    According to the Newton’s law of cooling, the rate of cooling depends upon the temperature difference between the temperature of body temperature of its surroundings.
    In general, T( t ) = Ta + ( Th – Ta )e -kt

    RE: Rate of Cooling Depends on the:

    The rate of cooling is also depends on area of the radiated surface because if the area of container in which the hot liquid type body is stored, area of cross section the container is directly proportional to the cooling.
    Rate of cooling also depends upon the nature of the radiating surface. Hence, all the factor are responsible for Rate of cooling.
