Section 2: States of Matter (Solid, Liquid, & Gas)

Deposition

gas to solid, without directly becoming a liquid

Temperature, what does it measure?

Temperature measures the average kinetic energy of molecules and atoms.

What is plasma?

Possible fourth state of matter high-energy state of atoms and molecules

What are the three states of matter?

Solids, Liquids, & gases

What is happening when to particles of a material when heat energy is transferred to the material and the temperature increases?

Temperature increases: molecules begin to move faster

Kinetic Molecular Theory

all molecules = constant motion & is different for the three states of matter

Normal Freezing Point

changes material from liquid to solid, at 1 atm

Normal Boiling Point

changes material from liquid to state, at 1 atm

Normal Melting Point

changes material from solid to liquid, at 1 atm

Vaporization

liquid to gas

Solid

molecules that have definite shape and volume & cannot be compressed

Liquid

molecules that have definite volume but not definite shape, and cannot be compressed

Gas

molecules that have indefinite shape and volume & can be compressed

Thermometers

number corresponding temperature

Sublimation

solid to gaseous state
