  • All matter is made up of extremely small particles

Particle Theory of Matter

2. All particles of one substance are the same. Different substances are made of different particles.

3. There are spaces between the particles.

4. The particles are always moving. The more energy that particles have, the faster they move.

5. There are attractive forces among particles. These forces are stronger when the particles are closer together.

particles far apart – force weak

particles close together – force strong

states of matter
States of Matter
  • SOLID
  • LIQUID
  • GAS
solid
SOLID
  • Strong attraction
  • Particles only vibrate
liquid
LIQUID
  • Weaker attraction
  • Particles move past each other
slide11
GAS
  • Attraction very weak
  • Particles far apart
classification of matter
Classification of Matter

MATTER

pure substances

mixture

elements

compounds

solutions

(homogenous

mechanical mixture

(heterogenous)

slide14

MATTER

anything that has mass and takes up space(eg. desk, ppl)

Pure substances

all “particles that make up the substance are the same (eg. water)

Mixture

contains 2 or more substances (eg. pizza, fruit punch)

Compounds

contain 2 or more elements in a fixed proportion

(eg. H2O, CO2)

Elements

cannot be broken down into simpler substances

(eg. carbon, oxygen)

Homogenousmixture (solution)

contains one visible component

(eg. tea, vinegar, fruit punch)

Heterogenous (mechanical) mixture

Contains more than one visible component

(eg. Italian salad dressing, raisin bran)
