Formula for density
density=mass over volume
What is density(no math terms)
How tightly packed matter is in a given volume
If an object sinks in the water, what can you say about the object’s density compared to water?
The object is denser than water
Weight
affect of gravity on mass
mass
the amount of matter in an object
volume
how much space an object takes up
matter
can not be created nor destroyed
anything that takes up space(has volume) and has mass
element
if all the atoms in the substance have the same identity
Substance
a type of matter with a fixed composition
molecule
two or more molecules combined
compound
a substance where the atoms of 2 or more elements are combined in a fixed proportion
mixture
putting 2 or more things together
heterogeneous
different materials that can be distinguished easily
homogenous
2 or more gaseous liquid or solid substance blended evenly throughout
