Principle

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

 

Benefits

  • 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.
