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.

Comprising two cast­metal uprights linked by a pair of parallel plated metal support rods and supporting an expansion bar at the top. Supplied with expansion bars. Comprising two cast-iron uprights, height 18 cm linked by two nickel plated rods supporting on expansion bar, length 38 cm fixed to one upright and resting on a friction pointer placed at the other. Supplied with scale reading 0 to 90 deg and one each of aluminium, brass and iron expansion bars.

Description

Demonstrates the difference in thermal conductivity of two different materials. The kit consists of two identical blocks, one made of aluminum and other made of plastic. When an ice cube is placed on aluminum it turns into water in seconds, while on plastic block it melts slowly. The aluminum block has a larger heat capacity and a higher thermal conductivity while the plastic block has lower values of both parameters. With instructions.

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.
