Thermal conductivity is a crucial engineering characteristic. When calculating heat conductivity, the device employs the guarded hot plate approach. A hot plate, or electrical heater, is sandwiched between two plates in this device. Two guard heaters are used to prevent heat loss from the hot plate, and water circulation helps to remove heat from liquids. Heater input controls the temperature

Experimental Objectives

• To determine the thermal conductivity of liquid
• To study of heat transfer through liquid .
