Solids

● Particles are locked in place and cannot move around
● Particles are vibrating (thermal energy)
● Have a fixed volume
● Have a fixed shape
● Least amount of energy

Liquids

● Particles can move around but must remain touching

other particles

● Have a fixed volume
● Does not have a fixed shape

○ Takes the shape of its container

● More energy than a solid

Gasses

● Particles have free movement
● No fixed volume

○ Gas be compressed

● No fixed shape
● More energy than a liquid

Plasma

● High energy gas
● Electrons are removed from the nucleus of atoms
● Plasma cutting torch, neon signs, lightening, stars

Multiple Choice

Which particle is "locked in place" and has very little movement?

• Solid

• Liquid

• Gas

• Plasma

Multiple Choice

Which particle is a high energy charged particle?

• Solid

• Liquid

• Gas

• Plasma

Multiple Choice

Which particle has movement but must continue to touch other particles?

• Solid

• Liquid

• Gas

• Plasma

Multiple Choice

Which particle has no restriction on movement?

• Solid

Density

● How much matter is in a space
● Density = mass / volume
● D = g / mL (liquids, gases, irregular solids)
● D = g / cm³ (regular solids)

Density

● Find mass

○ Use a scale

● Volume

○ Graduated cylinder

■ Liquids, gases, irregular objects

○ Ruler

■ Regular objects (cubes and such)
