What to Focus On
- Atoms and molecules are the building blocks of matter.
- Kanada’s Vaiseshika school described atoms as eternal and indivisible.
- Akasa is continuous and inert, unlike the four atomic elements.
- PV = KT is the starting gas relation for a fixed sample.
- PV = μRT is the perfect gas equation.
- R = 8.314 J mol⁻¹ K⁻¹ and k_B = 1.38 × 10^-23 J K⁻¹.
- Atoms are about 10^-10 m in size.
- In gases, interatomic distances are much larger than in solids and liquids.
- Mean free path is much larger than molecular size.
Common Mistakes to Avoid
Pressure of a gas depends only on the weight of gas molecules pressing downward.
The rms speed of a gas molecule is the same as the average speed.
Heavier gas molecules always move faster because they have more mass.
Memory Tips
Atomic hypothesis and the idea that matter is made of atoms
Boyle, Newton, and early attempts to explain gases
Ancient atomic thought in India and Greece
Four kinds of atoms in the Vaiseshika view
