States of Matter
The state of matter with a definite shape and a definite volume
Solid
Melting
The formula for finding density
Density = Mass/Volume
Molten rock beneath Earth's surface is called this
Magma
All matter is made up of these (be specific)
Atoms
This state of matter likes to move freely and has spread out particles
Gas
The process of going from a liquid to a solid
Freezing
What is the Greek letter "ρ" that defines density called?
In a food web, organisms that make their own food using sunlight or chemical energy are called this.
Producers
Groups of two or more atoms bonded together
Molecules

Evaporation
0.25 g/mL
Plants use sunlight, water, and carbon dioxide to make food through this process.
Photosynthesis
The density of water is this
1 g/mL

Sublimation
Find the density of an object with a mass of 75g and a volume of 12mL
6.25g/mL
This gas makes up about 78% of Earth's atmosphere.
Nitrogen
the natural movement of particles from an area of higher concentration to an area of lower concentration
Diffusion
Plasma
The process of going from a gas to a solid
Deposition
The units for density are always in the form of a:
