This is a tool that calculates the pressure, volume, number of moles or absolute temperature of an ideal gas, using the ideal gas law.

The tool is multi-directional and, therefore, determines the information that needs to be calculated based on which data has been entered. In other words, if three out of the pressure, volume, number of moles or absolute temperature are entered, the tool calculates the remaining one. When further data changes are made, the tool re-calculates the same gas law factor unless that factor is itself changed or a different data field is cleared.

In more detail, the information that can be entered and/or calculated is:

• The pressure of the gas, in kilopascal.
• The volume of the gas, in litres.
• The number of moles of the gas.
• The absolute temperature of the gas, in kelvin.
