States of matter

3 states of matter:solid,liquids and gases 

Which one you get depends on how strong forces of attraction are bewteen the particles.

How strong forces are depends on a)Material b)temperature c)pressure

TMP-TALL MEN POO

-strong forces of attraction bewteen particles

-dont move keep definate shape and volume

-particles vibrate about their positions the hotter

the solid becomes the more they vibrate(expand when heated)

-weak force of attraction bewteen particles

-definate volume but don't keep a definate shape

will take shape of container

-particles move in random motions.

-hotter the liquid get the faster they move.

(expand when heated)

-V.weak force of attraction bewteen particles 

-dont have definate shape/volume fill

container

-particles move constantly with random motion.

Hotter the Gas gets the faster they move (expand or pressure

increases when heated)

SUBSTANCES CAN CHANGE FROM ONE SUBSTANCE TO ANOTHER

Movement of particles

These experiments demonstrate diffusion:

Potassium Manganate: PM
