Heat transfer between two substances is affected by specific heat and the amount of time and area of physical contact between the substances.

Option D

Heat is transferred between two objects that have different temperatures. The object with high temperature transfers its energy to the object with low temperature.

The heat is transferred on the basis of three facts:

a) The temperature difference

b) Mass of the objects

c) Density of the subjects

The heat transfer is affected by the duration of the physical contact between the objects. The longer the duration, the more energy is transferred from the hot object to the cold object. The transfer of energy shall stop when both the objects have reached the same temperature.

The area of physical contact also affects the heat transfer. If a small hot object is in contact with a large cold object, the heat transferred shall be in accordance to the mass of the small object and only a portion of the cold one shall be affected.
