States of Matter

2. Definitions: Matter- anything that has mass and takes up space.
Mass- the amount of matter the object contains.
Which has a greater mass?

3. A. Kinetic Molecular Theory
KMT
Particles of matter are always in motion.
The kinetic energy (speed) of these particles increases as temperature increases.

4. B. Three States of Matter
Solids
very low KE - particles vibrate but can’t move around
fixed shape
fixed volume

5. B. Three States of Matter
Liquids
low KE - particles can move around but are still close together
variable shape
fixed volume

6. B. Three States of Matter
Gases
high KE - particles can separate and move throughout container
variable shape
variable volume
