Solid? Liquid? Gas?
Which one? How can you tell?
Four Key Principals
- All Substances are made up of tiny particles
- The particles are always moving/vibrating
- The particles have spaces between them
- The motion of the particles increase when the temperature increases and slows when they decrease
Solids
- Cannot Be Compressed
- Holds Its Shape
- Has a Fixed Volume
- Particles Vibrate In Place
- Particles have very little Space Between them
- Has the LEAST Kinetic energy
Liquids
- Change Shape To Their Container
- Has a Fixed Volume
- Particles are able to move around
- Particles are not connected
- LIttle space between particles
- Has MORE Kinetic energy than solids
Gases
- Take the shape of their container
- Take the volume of their container
- Particles are able to move around
- Most space between particles
- Has MOST kinetic energy
