Introduction

Properties of common gas materials are divided into following categories:

 

• Physical properties: Density, melting and boiling temperature.
• Mechanical Properties: Poisson's Ratio, bulk modulus, viscousity, kinematic viscousity.
• Acoustic Properties: Sound velocity.
 

  Note: 1. All properties are under 1 atm (1.01325×105 Pa; 760 mmHg; 14.6959 psi) and at room temperature 25 ºC (77 ºF) unless specified otherwise.
  2. Further information on a specific material can be obtained by clicking the name of that particular material in the following table.
  3. Users who prefer Standard or other unit systems rather than the SI units, click the amount (number) of the specific material property for unit conversion.
  4. Materials in different phases at room temperature: Solid, Liquid.
