Ideal gas

From Wikipedia, the free encyclopedia

An ideal gas is a gas with particular characteristics.

  • The particles have no volume
  • All collisions between particles have no effect on how fast those particles are going
  • The particles are not attracted to each other
  • They have random movement

The Ideal Gas Equation to work out the volume, pressure, temperature or amount of particles in an ideal gas is:

PV = nRT

Where n = number of moles of gas, T = temperature (K), R = 8.31, V = volume, P = pressure

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