Gas Law Apparatus

For demonstrating the different heat conductivities of five metals by observing the melting of wax.

The unit consists of a wooden base with upper and a lower platform. The upper platform has a hole to allow use as a simple circulation system with a single reservoir. Includes two glass basins and shaped glass tubes. This unit is used as an accessory with Pump / Turbine Unit (PH20425).

This simple unit can help the student understand the operating principle of pump and turbine. The unit consists of a rotor attached to a pulley via a shaft. It also includes 3 metal nozzles and a stopcock. When driven by a motor, the unit works as a pump, raising the water to higher potential energy. Whereas when the rotor is made to rotate by flowing water, the unit acts as a turbine.
