Matter is anything that has mass and takes up space. What is matter?
Particle Theory of Matter • 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.
Particle Theory of Matter 3. There are spaces between the particles.
Particle Theory of Matter 4. The particles are always moving. The more energy that particles have, the faster they move.
Particle Theory of Matter 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 • SOLID • LIQUID • GAS
SOLID • Strong attraction • Particles only vibrate
LIQUID • Weaker attraction • Particles move past each other
GAS • Attraction very weak • Particles far apart
Classification of Matter MATTER pure substances mixture elements compounds solutions (homogenous mechanical mixture (heterogenous)
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)
