9th Grade Chapter 5 Lesson 1

  1. 1. 9 Grade Chapter 5 th Lesson 1 Pgs. 110-119 For Student Use Only
  2. 2. Chemistry and Matter • Chemistry: – Study of materials and their function – Chemistry has been around for a long time – 1800s foundations for modern chemistry were made – Chemistry today is highly advanced
  3. 3. Chemistry and Matter • Matter: – Matter= anything that occupies space – Two pieces of matter cannot occupy the same space at the same time – Matter has inertia • Inertia- resistance to changes in motion • Newton’s 1st Law – Matter has mass • Amount of matter an object contains
  4. 4. Chemistry and Matter • Matter: – Matter CANNOT be created or destroyed under normal circumstances it only changes form – Matter has three basic shapes: • Solid= definite size and shape • Liquid= definite volume, no definite shape • Gas= no definite shape or volume – VOLUME= amount of space matter takes up
  5. 5. Chemistry and Matter • Matter: – 4th state of Matter: • Plasma= hot gas where atoms begin to break down (not found on Earth)= stars are made of plasma http://www.grc.nasa.gov/WWW/K-12/airplane/Images/state.gif
  6. 6. Chemistry and Matter • Composition of Matter: – John Dalton proposed the atomic theory of matter • All matter is made of atoms • Elements are made up of one kind of atom • Compounds are made up of more than one kind of atom • Molecules are made up of groups of atoms joined together
  7. 7. Chemistry and Matter • Matter – Elements are the “building blocks” of the universe. – As of 1995 there are 109 elements: • 88 occur naturally • 21 have been made in the lab
  8. 8. Chemistry and Matter • Matter – Atomic Symbols: • Standardized set of symbols for elements • Chemical symbol stands for element and is based on common or Latin name – Na= Sodium – C= Carbon – Pb= Lead – H= hydrogen – He= Helium
  9. 9. Chemistry and Matter • Matter in Motion: – Kinetic Energy: • Brownian Motion= molecules under microscope move • Kinetic Theory of Matter= molecules of matter are in constant motion – More energy= faster motion • Brownian Motion occurs because large objects will be collided on one side more than the other
  10. 10. Chemistry and Matter • Matter: – Diffusion= • Occurs from higher concentration to a lower concentration – Osmosis: • Concentration from higher to lower through a semi-permeable membrane
