Ideal Gas Law
Reference from the original Physics I textbook.
- Ideal Gas Law
The ideal-gas model treats molecules as particles of negligible volume whose interactions are negligible except during elastic collisions. Its equation of state is PV = nRT.
It assumes:
1. The collisions between the gas molecules and the wall are completely elastic, therefore there is no loss in kinetic energy.
- That gas molecules take up no volume.
- That there are no attractive or repulsive forces-also known as Van der Waals forces felt between molecules.

Ideal gas law
The ideal gas law relates absolute pressure, occupied volume, amount of gas, and kelvin temperature. The forms using moles and using particle count express the same state relationship with different constants. For example, heating a fixed amount of ideal gas in a rigid sealed container raises its pressure.
