In this internet-based activity, students investigate gas compressibility and gas expansion in a quantitative way. The end result will be an appreciation of Boyle’s Law and Charles’s Law.

By the end of this activity, students should be able to:

  • work with internet-based animations (Boyle’s Law and Charles’s Law) that allow scientific data to be recorded
  • describe in qualitative terms the relationship between the pressure exerted on a sample of gas at fixed temperature and its volume
  • develop a qualitative understanding of Boyle’s Law into a mathematical form of the law
  • describe in qualitative terms the relationship between the volume of a sample of gas and the temperature it is subjected to
  • use the Kelvin temperature scale
  • develop a qualitative understanding of Charles’s Law into a mathematical form of the law.
