PHY C10: Ideal Gases (Microscopic View)
Now let’s look on the scale of atoms & molecules, in a more in-depth QUANTITATIVE explanation and derivation of these equations:
- Equation for Gas Pressure
- Pressure in terms of density
- Kinetic Energy of a Gas Particle
- Relationship between Kinetic Energy & Temperature
- RMS Speed of Gas Particles
This is a long & (slightly boring) one, so stay strong!
