Ice Melting Kit
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.

Charle’s Law Apparatus
To determine co-efficient of expansion of a gas at constant pressure. A glass U-tube with a bulb and stopcock at one end, the other limb being open. An outlet tube from the bottom of the U tube passes through a rubber bung and has a stopcock at the end. The stem below the bulb is graduated 3 x 0.1 ml. An inlet tube with a mohr clip also passes through the bung. A glass water jacket encloses the U tube. All glass parts made of borosilicate glass requires only 20 ml mercury, which is not included.
