......and we are BACK! Well, now we are back to applying the particle model to help explain why substances will expand, contract, melt, boil, freeze, etc. It's really an important concept for almost everything in life: You put more energy into your work, you are gonna get BETTER BIGGER results! Particles of matter are the same: They get more energy in them, they are going to get larger too. (except water -that's the exception).
-Today is Tuesday and it's 80 degrees out. THE AIR PARTICLES are MOVING FASTER because they've got more ENERGY in them. The hot AIR will rise BECAUSE IT'S LESS DENSE now.
-I strongly suspect you are not reading this on TUESDAY, but if you play the games below on the links this week, they'll help you "get it" .
