Abstract: Determination of thermal conductivity of substance is required in engineering applications. Fourier proposed law for heat conduction that is heat flow rate is directly proportional to area and temperature gradient. Thermal conductivity is ability of material to transfer heat. It is also called as thermal conductivity coefficient. Thermal conductivity varies widely for various engineering materials and it is function of temperature, density and structure. Purpose of this paper is to calculate thermal conductivity of powder, liquid. In this we measured thermal conductivity of plaster of Paris (POP), Water and compared those values with standard values.in this paper we also present variation of temperature with respect to thickness.

Keywords: Thermal conductivity, Heat transfer, conduction, Heater, Temperature sensor etc…
