mass/volume
the amount of matter in a given space
What is density
100
that which has mass and occupies space
What is matter
200
the science of matter and energy and their interactions
What is physics
200
the amount of 3-dimensional space occupied by an object or the space that something contains
What is volume
200
a fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors
What is plasma
300
the study of the properties of matter and how matter changes
What is chemistry
300
a body of matter without definite shape
What is mass
300
of definite shape and volume
What is solid
300
describes a process in which heat is absorbed from the environment
What is endothermic

What is weight
400
a substance in the fluid state of matter having no fixed shape but a fixed volume
What is liquid
400
chemical reaction in which energy is primarily given off in the form of heat
What is exothermic
500
a proposal intended to explain certain facts or observations
What is a hypothesis
500
the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force
What is inertia
