Ideal Gases

An Ideal Gas is a theoretical model of a gas. It is defined by the following assumptions: 

• The molecules are point particles – with negligible volume
• The molecules obey the laws of mechanics
• An ideal gas can not be liquefied or solidified
• Molecules have a variety of speeds and move randomly
• There are no forces between the molecules except when the molecules collide
• The duration of a collision is negligible compared to the time between collisions
• The collisions of the molecules with each other and with the container walls are elastic
