States of Matter Study Guide

Test: Thursday, February 9, 2012

Things to Know/Review:

·       Chapter 11 in your textbook (pages 313-343)-use chapter review to help you study! J

·       Be able to describe the particles in a solid, liquid, and gas

o   Solid: particles close together, fixed position, organized

o   Liquid: particles close together, slide past one another (no fixed position)

o   Gas: particles far apart, no fixed shape or volume

·       Be able to describe the particles when changing states

o   From solid to liquid; from liquid to gas; from gas to liquid; from liquid to solid

§  For example, when a solid becomes a liquid, the particles  begin to move slowly, spread out, and slide past one another.

§  When do you add heat?  When do you take away heat?

§  Google “Study Jams Matter” for video, song, vocab, and quiz!

·       Define matter (anything that has mass and takes up space)

·       Evaporation is the change from liquid to gas (so what happens to the particles?)

·       Condensation is the change from gas to liquid (so what happens to the particles?)

·       Difference between physical and chemical changes (and some examples of each)

·       Describe density and why some things sink and some things float
