Is thermal conductivity and conduction same?

They are the same. They have the same units, same definition. Thermal conductivity is the ability of a material to conduct heat. High conductivity materials conduct heat well.

What is difference between thermal conductivity and thermal resistance?

Thermal conductivity is a material property and describes the ability of the given material to conduct heat. Thermal resistance is another inherent thermal property of a material, and is the measure of how a material of a specific thickness resists the flow of heat.

What is meant by thermal conductance?

Thermal conductance is the time rate of steady state heat flow through a unit area of a material or construction induced by a unit temperature difference between the body surfaces, in W/m2⋅K.

What is the difference between thermal conductivity?

The key difference between thermal conductivity and diffusivity is that thermal conductivity refers to the ability of a material to conduct heat whereas thermal diffusivity refers to the measurement of the rate of transfer of heat of a material from its hot end to the cold end.

What is the relation between conductance and conductivity?

Conductance is the extrinsic property, whereas the inherent property is conductivity. This suggests that conductance is an object’s property depending on its quantity/mass or physical form and scale, whereas conductivity is the object’s intrinsic property of the substance.

What is the relation between thermal resistance and thermal conductance?

Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of thermal conductance. (Absolute) thermal resistance R in kelvins per watt (K/W) is a property of a particular component.

What is true about thermal conductivity?

Thermal conductivity is the property of a material to conduct heat. Heat transfer occurs at a lower rate across materials of low thermal conductivity than across materials of high thermal conductivity. This property is temperature dependent and its reciprocal is thermal resistivity.

What is difference between conductivity and electrical conductivity?

Conductivity is usually denoted by the Greek letter σ. The SI unit of conductivity is siemens per meter. It must be noted that conductivity is specifically a property of the material at a given temperature. The conductance is a property of the object whereas electrical conductivity is a property of the material.

What is the difference between conductivity and conductivity?

Conductance is a property of the component but conductivity is a property of the material. Conductance depends on the dimensions of the conductor, but conductivity does not depend on the dimensions. Conductance is measured in Siemens while conductivity is measured in Siemens per meter.
