3.boiling point
4.melting point
5.density
6.solubility
7.electric conductivity
8.malleability
9.ductility

Hypotheses
a tentative explanation or prediction based on experimental observation
Laws
a concise verbal or mathematical statement of a behavior or a relation that is consistently observed in nature without contradictions
Theory
A well-tested, unifying principle that explains a body of facts and the laws based on them
State of Matters
Solid, liquid, gas and plasma
Kinetic-Molecular Theory of Matter
1.Solid
2.Liquids
3.Gas
1. particles are closely packed, usually in a regular array. The particles vibrate, but don’t make large movements
2. particles are arranged randomly. Particles can move past one another
3. particles are typically far apart and moving very rapidly.
Kinetic-Molecular Theory of Matter
Solid – particles are closely packed, usually in a regular array. The particles vibrate, but don’t make large movements
Liquids – particles are arranged randomly. Particles can move past one another
Gas – particles are typically far apart and moving very rapidly.
