States of Matter

States
1. Solid: fixed shape and volume. Particles packed together tightly in a fixed pattern, strong forces holding them together, they can only vibrate
2. Liquid: fixed volume, takes shape of container, flows. Particles can move and slide past each other, with weaker forces of attraction.
3. Gas: no definite volume or shape, spreads out to fill container. Lighter than same volume of liquid or solid. Particles are far apart, with almost no forces of attraction, and collide and bounce off in all directions
4. Flat line on a heating curve shows a change of state
Diffusion: gas particles mix by colliding randomly with each other and bouncing off in all directions
1. Mass of particles and temperature affect rate of diffusion
  1. The higher the temperature, the more energy the particles have, the faster they move and diffuse
  2. The lighter the particles, the easier they will move, the faster they will diffuse
Pressure: the force which gases exert on the sides of their container
1. Space in container and temperature affect pressure
  1. The higher the temperature, the more energy the particles have and the more they move, colliding more frequently and forcefully with the sides of their container
  2. If a gas is compressed, the particles have less space to move and are in a smaller space, so they collide with the container and each other more often
