Particle Model of Matter
- Explains the three states of matter
- Solid
- Fixed, regular arrangement
- High density
- Vibrate slightly
- Liquid
- Particles can move
past each other easily
- Less dense
- More energy than solids
- Gas
- Free to move independantly
- low density
- high energy
- Density
- Density = mass/volume
- you can measure density by measuring water
displacement with a eureka can then using the
displaced water as your volume for the object
- Internal energy
- Internal energy is the energy the
particles have as a combination of their
kinetic and potential energy stores
- specific latent heat
- energy goes into breaking bonds
instead of increasing temperature
- The energy needed for 1 kg of
a substance to change state
- Energy = mass * specific latent heat
- Pressure and gasses
- When gasses collide with a
container, pressure occurs as
the net force pushes outwards
- Pressure and volume are inversely
proportional at a constant temperature
