Question

The direction in which heat flows between two bodies depend on their

Answer 1

Depends upon the temperature of neighboring elements

Explanation:

• The equations of heat flow in solids does not depend on which way flows up.
• The direction of heat flow in a small element within a solid  depends on the temperature of its neighboring elements.
• It is due to the fact that only neighboring element can decide that heat can pass from the system or into the system.
• Heat normally flows from hot substance to cold substance.
