Physics P2: Kinetic Molecular Model of Matter

## 1. States of Matter

### 1.1. Gas

1.1.1. Particles far apart from each other, and move around freely. Warmer than both liquids and solids of the same substance, and bonds between the particles are not present. Can fill almost any shape, because they are compressable, and don't have a fixed volume. No force, except when the molecules collide.

### 1.2. Liquid

1.2.1. Particles tightly packed, but can slide around each other. Still aslo vibrating, but faster than particles in a solid. Generally warmer than a solid, the bonds between the particles aren't as strong, so the bonds can shift around. Still incompressible, and have a fixed volume, but no fixed shape. Weak forces between molecules

### 1.3. Solid

1.3.1. Particles tightly packed, and bonded together. Still vibrating, but cannot adapt to the container that they are in. They are incompressible, have a fixed volume, and a fixed shape. Regular pattern. Strong forces between molecules

## 2. Information

### 2.1. Absolute Zero

2.1.1. When molecules no longer shake or move.

2.1.2. -273 Degrees Centigrade, and Zero Degrees Kelvin.

2.1.3. No more energy can be extracted from molecules making up matter.

### 2.2. P, V, T

2.2.1. P is the collisions with the inside of the container (Pressure)

2.2.2. T is how fast the particles are moving (Temperature)

2.2.3. V is the Volume of the container

2.2.4. As the pressure and temperature go up, the volume is constant.

2.2.5. As pressure increases and the volume decreases, the temperature must be constant.

## 5. Pressure

### 5.2. Boyle's Law

5.2.1. P1V1=P2V2

5.2.1.1. Pressure One Multiplied by Volume One is equal to Pressure Two Multiplied by Volume Two, if the amount of gas is equal in both experiments.
