1/6/16 warm up Please have your SLG HW ready
Solids – definite shape, definite volume • Liquids–definite volume, no definite shape takes the shape of the container • Gases-no definite shape, no definite volume; fills the container…volume changes*
Independent work • P 68 -70 • Draw particle view of Cu, Hg, and He • Label position of particles (atoms) • FINISH FOR HOMEWORK • EXTRA - REDO ON COMPUTER?
Why solid? • “Copper atoms are packed close together in an orderly arrangement”
1/7/16 warm up • Please open notebook to your nanoscopic / particle view of Cu, Hg, and He.
Why solid? • “Copper atoms are packed close together in an orderly arrangement”
Why liquid? • “The mercury atoms are close together but their arrangement is more random than the arrangement of atoms in copper. ” • Mercury atoms can slide past each other mercury atoms can flow
Why gas? • “The helium atoms are…at random locations throughout the balloon. There is more space between two helium atoms in the balloon…”
1/7/16 HW assignment Need : Internet, printer Assignment : Brainpop video / print quiz “States of Matter” Due: Monday 1/11/16 ( 10 points) Extra – pause video on nanoscopic / zoom / particle view. Think think…
Practice with particles - Please think about my background
Particle Practice 1. What does the textbook p 68 -70 have to say about: Solid particles liquid particles gas particles? Orderly close together spaced Arrangement more random (crystals) “slide freely” “fill container”
