ⓘ Ideal gas

An ideal gas is a gas with particular characteristics.

• The particles have no volume
• The particles neither attract each other nor repel
• All collisions between particles are elastic collisions and lose no kinetic energy
• They have random movement

Ideal gases are hypothetical which means that they do not exist in their true form.

1. Equation

The Ideal gas law that relates the volume, pressure, temperature and number of particles in an ideal gas is:

P V = n R T {\displaystyle PV=nRT}

Where:

• T = temperature in Kelvin K
• P = pressure in Pascals Pa
• n = number of moles of gas
• V = volume in Litres L
• R = 8.314 J⋅K −1 ⋅mol −1, which is the universal gas constant
