Gas Laws HD Lite

Two simulations in one, this mini application gives beginning chemists experience with Boyle's law and Charles's law when they are learning about relationships between pressure and volume, and between temperature and volume. As one property is adjusted, see how it affects the other!

App Overview

  1. From the home screen, choose between Boyle's Law and Charles's Law
  2. In the Boyle's Law section, find a plunger and a pressure monitor
  3. Adjust the volume on the plunger and read the pressure from the pressure gauge
  4. By pressing the Mode button, three different units for pressure can be selected: atmospheres, mmHg, or kPa
  5. Learners are instructed to record volume and pressure, and then plot the values on a graph to determine how they relate
  6. The Charles's Law feature presents an adjustable temperature and a closed cylinder in which a piston moves according to the volume
  7. Vary the temperature, record it and the volume, and then plot them on a graph

Instructional Ideas

After introducing these gas laws, and prior to experimenting with them in the laboratory, give budding scientists little time to carry out both activities as directed in the instructions.

Classroom Considerations

This is a very simplistic activity, but a nice alternative to just presenting data in a table for budding scientists to graph.


  • Provides practical reinforcement of concepts

  • Very limited application
