Overview
The Thermal Conductivity of Liquids apparatus allows precise measurement of the thermal conductivity of various liquid samples. A thin heater or hot wire is immersed in the liquid sample contained in an insulated cell. By measuring the temperature rise and heat input, the thermal conductivity is calculated using Fourier's law. The experiment demonstrates how thermal conductivity of liquids varies with temperature and type of fluid. It provides essential data needed for heat exchanger design and helps students understand molecular-level energy transport mechanisms in liquids.
