States of Matter

Matter is everything that occupies space.
Matter exists in different physical states: Solid, Liquid, Gas, Plasma, Bose-Einstein Condensate.
Solids, Liquids, and Gases are the most common states of matter.
Plasma is a highly ionized gas, composed of free ions and electrons.
Plasma is prevalent in stars, lightning, and fluorescent lights.
Bose-Einstein Condensate is the fifth state of matter, formed at extremely low temperatures.

Properties of Gases

Gas molecules are far apart and move constantly.
Gas molecules experience elastic collisions, conserving their kinetic energy.
Diffusion: Gas molecules spread out to fill their container due to their free movement.
Effusion: Gas molecules escape through small holes into a vacuum.
Gas molecules exert pressure due to their collisions with the container walls.
Boyle's Law: At constant temperature, the pressure of a gas is inversely proportional to its volume.
Pressure is the force applied per unit area.

Units of Pressure

Pressure is measured in Pascals (Pa) in the International System of Units (SI).
Other pressure units include atmospheres (atm), millimeters of mercury (mmHg), and torr.
1 atm = 101325 Pa = 760 mmHg = 760 torr.

Boyle's Law Example

Boyle's Law states: P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
If a gas's initial pressure is 3 atm and volume is 5 L, and the pressure is reduced to 2 atm, then the final volume will be 7.5 L.

Units of Volume

Volume is frequently expressed in liters (L) or milliliters (mL).
Other units include cubic meters (m³) and cubic centimeters (cm³).
