Question

The direction of heat transfer depends on which of the following?

• A. Mass of each body.
• B. Amount of heat contained in each body.
• C. Temperature of each body.
• D. Shape and size of the body.

Answer 1

The correct option is C

Temperature of each body.

Direction of heat flow depends only on the temperature of the bodies.
Heat is a form of energy. Heat flows only when there is a temperature difference.
Heat always flows from higher temperature to lower temperature, irrespective of heat energy possessed by the bodies in contact.
