Differentiate between Thermal Conductivity and Electrical Resistivity of various metals?
Explanation:
Thermal conductivity-
Thermal conductivity is one of the three methods of heat transfer. It refers to the intrinsic ability of a material to transfer or conduct heat. Thermal conductivity occurs through molecular agitation and contact, and does not result in the bulk movement of the solid itself. Heat moves along a temperature gradient, from an area of high temperature and high molecular energy to an area with a lower temperature and lower molecular energy. This transfer will continue until thermal equilibrium is reached. Correspondingly materials of high thermal conductivity are widely used in heat sink application and materials of low thermal conductivity are used as thermal insulation. The reciprocal of thermal conductivity is called thermal resistivity.
