What law states matter cannot be created or destroyed?
Law of Conservation of Mass
What law says energy cannot be created or destroyed?
What is Newton's First Law also called?
Law of Inertia - Objects in motion stay in motion, objects at rest stay at rest unless acted upon by another force.v

What is the difference between an element and a compound?
Element = one type of atom; Compound = two or more elements chemically bonded
Give an example of energy transformation.
Chemical -> mechanical, electrical -> light, etc.
What is the formula for force?
F = m * a
What does the atomic number tell you?
How does heat flow?
From the hotter object to the cooler object until they are both the same temperature (equilibrium).
