Thermal expansion in liquids

Prinicple

The volume expansion of liquids is determined as a function of temperature.

Tasks

Determine the volume expansion of n-heptane (C7H16), olive oil and water as a function of temperature, using the pycnometer.

Thermal and electrical conductivity of metals

Principle

The thermal conductivity of copper and aluminium is determined in a constant temperature gradient from the calorimetrically measured heat flow. The electrical conductivity of copper and aluminium is determined, and the Wiedmann-Franz law is tested.
