+ Introduction

There are three modes of heat transfer namely conduction, convection and radiation.

Conduction : Conduction refers to the heat transfer that occurs across the medium. Medium can be solid or a fluid.

Convection : Convection refers to the heat transfer that will occur between a surface and a moving fluid when they are at different temperatures.

Radiation : In radiation, in the absence of intervening medium, there is net heat transfer between two surfaces at different temperatures in the form of electromagnetic waves.

Fourier's law (Conduction)

The law of heat conduction, also known as Fourier's law, states that the rate of heat transfer through a material is proportional to the negative gradient in the temperature and to the area, at right angles to that gradient, through which the heat flows.

Newton's law of cooling (Convection)

Newton's law of cooling states that the rate of heat loss of a body is directly proportional to the difference in the temperatures between the body and its surroundings.

Stefan Boltzmann law (Radiation)

The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature.

The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by, or. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.

Thermal conductivity
04:22

In gases and liquids, conduction is due to the collisions and diffusion of molecules during their random motion.

Heat conduction in gases
06:24

Fourier's law

The law of heat conduction, also known as Fourier's law, states that the rate of heat transfer through a material is proportional to the negative gradient in the temperature and to the area, at right angles to that gradient, through which the heat flows.

Interpretation Of Fourier's law
05:08

Heat conduction in solids is similar to the conduction of electricity in electrical conductors in many aspects. In a conductor, the flow of electricity is driven by a potential difference and so is the flow of heat driven by a difference in temperature.

Electrical analogy of heat transfer
