STATES OF MATTER

PHYSICAL PROPERTIES

• Density
• Shape
• State of matter
• Texture
• Color

4 STATES OF MATTER

• Solid
• Liquid
• Gas
• Plasma

SOLIDS

• Have a definite shape and volume
• Particles are packed closely together
• Very little energy so particles only vibrate
• Particles have tight bonds and are packed closely together

LIQUIDS

• The volume is definite but takes the shape of any container
• It has more energy which allows it to flow
• Particles are loosely packed with loose bonds

GASES

• No definite shape or volume
• Has lots of energy and moves at high speeds
• Particles are not connected so they are free to move

PLASMA

• No definite shape or volume
• Extremely fast with high energy
• No bonds between particles
• Not that common on Earth

PHASES CHANGE- to ADD or REMOVE (heat) ENERGY

• Melt- change from solid to liquid
• Freeze- change from liquid to solid
• Condensation- change from gas to liquid
• Boil- change from liquid to gas
• Sublimate- change from solid to gas

Temperature stays the same during a phase change

Phase changes do NOT occur because of temperature but because ENERGY is either ADDED or REMOVED
