Definitions:

Atomic Hypothesis: All things are made of atoms - little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another.

Laws of definite and multiple proportions:

First Law- The first law says that any given compound has a fixed proportion by the mass of its constituents.

Second Law- The second law says that when two elements form more than one compound, for a fixed mass of one element, the masses of the other elements are in a ratio of small integers.

Gay Lussac’s Law: When gasses combine chemically to yield another gas, their volumes are in the ratios of small integers.

Mean Free Path: The average distance a molecule can travel without colliding is called the mean free path.

Ideal Gas: A gas that satisfies exactly at all pressures and temperatures is defined to be an ideal gas.

Charle’s Law- for a fixed pressure, the volume of a gas is proportional to its absolute temperature T.

Boyle’s Law- Keeping temperature constant, pressure of a given mass of gas varies inversely with volume.

Law of Equipartition of Energy- In equilibrium, the total energy is equally distributed in all possible energy modes, with each mode having an average energy equal to ½ k T. This is known as the law of equipartition of energy.

Formulas:
