  1. STATES OF MATTER CH. 3 SECTION 1

  2. SOLID • HAS A DEFINITE SHAPE • HAS A DEFINITE VOLUME • KEY - THE PARTICLES IN A SOLID ARE CLOSELY LOCKED IN POSITION AND CAN ONLY VIBRATE • EXAMPLE – TABLE, BOOK, ICE, …ETC

  3. COPY SOLID PARTICLES

  4. TYPES OF SOLIDS

  5. TYPES OF SOLIDS • CRYSTALLINE SOLID- SOLIDS THAT ARE MADE UP OF CRYSTALS. MELTS AT DISTINCT TEMP. • EXAMPLE- SALT, SUGAR, SNOW • AMORPHOUS SOLID- PARTICLES ARE NOT ARRANGED IN A REGULAR PATTERN. DOES NOT MELT AT DISTINCT TEMP. • EXAMPLE- PLASTICS RUBBER AND GLASS

  6. SALT IS A _________ _______

  7. Types of SOLIDS give 3 more examples

  8. Plastics can harm marine life. Why?

  9. LIQUIDS • HAS A DEFINITE VOLUME • TAKES THE SHAPE OF ITS CONTAINER • KEY- PARTICLES IN A LIQUID ARE MORE LOOSELY CONNECTED AND CAN COLLIDE WITH AND MOVE PAST ONE ANOTHER. • FLUID- A SUBSTANCE THAT FLOWS • EX- WATER, OIL, MILK

  10. Copy types and name 3 more

  11. COPY LIQUID PARTICLES

  12. PROPERTIES OF LIQUIDS • SURFACE TENSION- AN INWARD PULL AMONG THE MOLECULES OF A LIQUID THAT BRINGS THE MOLECULES CLOSER TOGETHER. • EX- A FULL GLASS OF WATER CAN BE HIGHER THAN THE RIM. • VISCOSITY-LIQUIDS RESISTANCE TO FLOWING • EX- HIGH VISCOSITY- SLOW FLOW- HONEY • EX- LOW VISCOSITY- FAST FLOW- WATER

  13. What other types are there?

  14. GASES • NO DEFINITE VOLUME • NO DEFINITE SHAPE • IS A FLUID –FLOWS • KEY- PARTICLES SPREAD APART MOVING IN ALL DIRECTIONS FILLING THE SPACE OF ITS CONTAINER. • KEY- THE ATOMS AND MOLECULES ARE FREE TO MOVE INDEPENDENTLY AND COLLIDE FREQUENTLY. • EX- AIR, HELIUM, NITROGEN.

  15. Types of gases name 3 more • Examples of Gases • air. • helium. • nitrogen. • freon. • carbon dioxide. • water vapor. • hydrogen. • natural gas.

  16. COPY GAS PARTICLES

  17. BRAIN POP • http://www.brainpop.com/science/matterandchemistry/statesofmatter/

  18. ASSESSMENT QUESTIONS • P. 95 • Q AND A • #1-BC, #2-AB, #3 AB
