Define THIS!
This is defined as the seemingly random motion of particles suspended in a fluid due to collisions with particles of the fluid.
What is Brownian motion?
The general classification (pure substance/mixture) of water.
What is a pure substance?
This state is characterized by a fixed shape.
What is a solid?
The change of state from solid to liquid.
What is melting?
This is the mathematical definition of density.
What is mass per unit volume or:
rho=m/V
This is an example of non-matter.
What is energy (light, heat, sound)?
This is defined as the tendency of substances to spread out due to the random motion of its particles.
What is diffusion?
The general classification (pure substance/mixture) of oatmeal cookies.
What is a mixture?
This state is characterized as a fluid with low density.
What is a gas?
The change of state from gas to liquid.
What is condensation?
The result when you rearrange the density equation to solve for mass.
What is:
m=rhoV
These are the two categories of pure substances.
What are elements and compounds?
This is defined as the ratio of material's mass to its volume.
What is density?
The specific classification (element/compound/homogenous mixture/heterogenous mixture) of iron.
What is an element?
This state is characterized by the tendency of its molecules to expand to fill the bottom of a container.
What is a liquid?
The definition of deposition.
The change of state from gas to solid.
The result when you rearrange the density equation to solve for volume.
What is:
V=m/rho
These are the two categories of mixtures.
What are homogenous and heterogenous?
Matter is defined as anything that possesses these two physical properties.
What are:

The specific classification (element/compound/homogenous mixture/heterogenous mixture) of sodium chloride.
What is a compound?
These states are characterized by their relative incompressibility.
What are solids and liquids?
The definition of sublimation.
What is the change of state from solid to gas?
This quantity is measured in units of cc's, ml, or gallons.
What is volume?
These types of properties can be observed without altering chemical composition.
What are physical properties?
This Law states that when substances react to form new compounds, the do so in integer ratios.
What is the Law of Definite Proportions?
The specific classification (element/compound/homogenous mixture/heterogenous mixture) of sweet tea.

Vaporization can occur in these two ways, one quickly, the other slowly.
What are boiling and evaporation?
kg/m3 and g/cc are units of this quantity.
What is density?
These are the two nuclear processes during which matter is NOT conserved.
