  • What Are Thermal Properties of MaterialsWhat Is Heat Capacity?Major Components of Thermal PropertiesThermal properties are those properties of a material which is related to its conductivity of heat. In other words, these are the properties that are exhibited by a material when the heat is passed through it. Thermal properties come under the broader topic of the physical properties of materials. Thermal properties of material decide how it reacts when it is subjected to heat fluctuation (excessive heat or very low heat, for example).
