Thermal expansion in solids and liquids

Principle

The volume expansion of liquids and the linear expansion of various materials is determined as a function of temperature.

Benefits

• With detailed experiment guide
• Two experiments in one

Tasks

1. To determine the volume expansion of ethyl acetate (C4H8O2), methylated spirit, olive oil, glycerol and water as a function of temperature, using the pycnometer.
2. To determine the linear expansion of brass, iron, copper, aluminium, duran glass and quartz glass as a function of temperature using a dilatometer.
3. To investigate the relationship between change in length and overall length in the case of aluminium.
