What form of matter is this

gas

what form of matter is this

solid

what form of matter is this

color, hardness, conductivity, melting/boiling point

physical properties of matter

reactivity, flammability, ability to rust

chemical properties of matter

the atoms or molecules move faster and far apart

what happens if you heat a solid?

the molecules or atoms move slower and closer together

what happens if you cool a solid?

extensive property

a property that depends on the amount of matter in a sample. (mass, volume, internal energy)

intensive property

a property of matter that depends only on the type of matter in a sample and not on the amount. (ex: color, temperature, density, solubility)
