Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Ideal gas law | The ideal gas law can be viewed as arising from the kinetic pressure of gas molecules colliding with the walls of a container in accordance with Newton's laws. |
Real life uses :
To better understand the behavior of gases.
Places to visit :
Physics laboratory.
Practical examples around us
| Examples | Explainations |
|---|---|
| Maxwell-Boltzmann ideal gas, | Real fluids at low density and high temperature approximate the behavior of a classical ideal gas. |
What you learn in Theory:
A gas behaves more like an ideal gas at higher temperature and lower pressure, as the work which is against intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
What you learn in Practice:
The ideal gas model tends to fail at lower temperatures or higher pressures, when intermolecular forces and molecular size become important.
