Compound Bar

Description

Comprising five removable glass tubes in a sliding frame and supported in a water trough. For demonstrating the different thermal expansions of various liquids. Comprising five glass tubes in a frame and supported in a water trough. The frame has a special sliding arrangement with clips to hold glass bulbs with tubes. The bulbs can be easily removed and fixed and have funnel formation on top for easy filling.

Description

Metal, for experiments on specific heat of different metals, cylindrical metal blocks 1 Kg ± 2%. Each block has a central hole for a special immersion heater and an offset hole for Thermometer.

Description

To illustrate expansion of metal on heating and contraction on cooling, with steel bar of length 100 x 10 mm and plated brass gauge with a cutout to just accommodate the bar and two holes through which the bar passes when cold.

Description

Demonstration Apparatus for Illustration of Thermoexpansion. A 12 V Halogen bulb is fitted below the bi-metallic strip. When heated the strip bends upward and breaks the circuit.
