Question

What direction does heat move?

Answer 1

Hint: Heat of a body is the measure of temperature of the body. It can be described as the energy that flows from one body to the other due to the difference in temperatures between the bodies. Heat is transferred to another body through different ways which are discussed below.

Complete step-by-step solution:
Heat flows in the direction of temperature gradient. Heat energy flows from a point that is at higher temperature to a point that is at lower temperature or in simple words from a hot body to a cold body until and unless both the points reach the same temperature.
Additional information: Heat transfer is carried out in three ways namely: conduction, convection and radiation.
Conduction is the transfer of heat from a body at higher temperature to a body at lower
temperature through the particles of the bodies which are in contact with each other. There is no actual movement of the particles from one place to the other.
Convection is the transfer of heat when the particles of the body actually displace from their
positions to transfer the heat energy or thermal energy.
Radiation is the transfer of heat that requires no medium to occur.

Note: Heat energy can never flow from a body at lower temperature to a body at higher temperature naturally. Heat energy being transferred to a body at lower temperature is a stable position and we know that the universe has a tendency to go towards the equilibrium, hence this happens.
