Thermal Conductivity is the property of a material that indicates its ability to conduct heat.

Thermal Conductivity is defined as the quantity of heat transmitted during time through thickness in a direction normal to a surface of area A due to temperature difference under steady state conditions and when the heat transfer is dependent only on the temperature gradient.

Thermal Conductivity can be represented by symbol K. The more modern symbol for thermal conductivity is the Greek lambda. It is used primarily in Fourier's law for heat conduction.

Thermal Resistance can be defined as measure of a body's ability to prevent heat from flowing through it, equal to the difference between the temperatures of opposite faces of the body divided by the rate of heat flow. It can also be termed as Heat Resistance.

Thermal Conductance can be defined as amount of heat transmitted by a material divided by the difference in temperature of the surfaces of the material. It can also be termed as Conductance.

The term Specific Heat was originated primarily through the work of Scottish Physicist Joseph Black. Specific Heat is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval.
