D = m/V
100
This state has a fixed shape. It does not take the shape of its container.
Solid
100
Solid to liquid
Melting
100
How much space something takes up.
Volume
100
Amount of matter in an object
Mass
200
This state has a lot of space between the particles, and they move around quickly in all directions
Gas
200
Liquid to solid
Freezing
200
Explains why metals are used in electrical wires to move electricity from one place to another, and not plastic.
Conductivity
200
What is the density of an object that has a volume of 10 mL and a mass of 500 grams?
50 g/mL
300
In this state, the particles can slip and slide by each other.
Liquid
300
Liquid to gas
Vaporization/ Boiling
300
The formula to calculate the mass of an object, if you are given its volume and density.
Mass = density x volume, or m = d x V
