Activity

Gas properties

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.

General gas law constant: Temperature, Volume & Pressure diagram

The general gas law

For a fixed amount of gas, the relationships between gas volume, gas temperature and gas pressure can be combined to give the equation known as the general gas 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.
