whats conductivity
materials ability to allow heat to flow
What is precipitate?
Liquid turning to solid
Which is more compact: solid, liquid, or gas?
Solid
Law of conservation of energy?
Energy can't be created or destroyed
gas to solid

viscosity
tendency of a liquid to resist flowing
Endothermic vs exothermic?
Exothermic: releases heat, endothermic: absorbs heat
Filtration vs distillation?
Filtration is separating materials based on particle size and distillation is separating is based on boiling points
