States of Matter
Condensation
gas --> liquid
The state of matter molecules move the fastest
gases
Boiling point
Heat increases speed of liquid water molecules, 100 celsius reached, molecules escape the liquid and become invisible water vapor (gas)
Melting point
Heat makes water (ice) molecules move fast, 0 celsius reached, ice melt and becomes liquid water
Boiling
liquid --> gas
Evaporation
liquid --> gas
Freezing
liquid --> solid
Melting
solid --> liquid
Three states of matter
solid, liquid, and gas
The state of matter molecules move the slowest
solids
solid
water molecules are close together and vibrate, definite size, fixed shape
liquid
water molecules brush against/slide past each other, definite size, shape of container
gas
water molecules moving freely, no definite size or shape
