Temperature related material properties

Temperature-related properties of materials are the properties that change or show any variation with temperature variations. Various properties of materials include physical properties, mechanical properties, chemical properties, electrical properties, magnetic properties, etc. The chemical, electrical, and magnetic properties of materials are important, but the physical and mechanical properties are more important. Based on their composition and chemical bonding, materials are classified as metals, ceramics, polymers, and composites.
