WHMIS
Workplace Hazardous Materials Information System
fluid
is anything that has NO fixed shape and can Flow
Slurries
mixtures of water and solids
Pure substances
made of only 1 KIND OF MATTER
Mixtures
2 or more substances combined together
mechanical mixtures
you can SEE the different substances that make up the mixture
HOMOGENEOUS MIXTURES
CAN'T see the different substances that make up the mixture
Solutions
looks like it is one substance
Suspensions
cloudy mixture where tiny pieces are held within the substance
Colloids
a cloudy mixture, but the tiny particles are so small that they DO NOT separate out easily
chromatography
can be used as a TEST to determine whether a substance is pure or a solution
SOLUTE
The substance that DISSOLVES
SOLVENT
The substance that DOES the DISSOLVING
Dilute solutions
have small amounts of solute compared to solvent
Concentration
solution tells you the amount of solute (powder, etc..) dissolved in a specific amount of solvent
Unsaturated solutions
where MORE solute (solid) CAN be dissolved
Saturated solutions
where NO MORE solute (solid) can be dissolved at a GIVEN temperature
Solubility
the MAXIMUM amount of solute you can add to a fixed volume of solvent at a given temperature
Saturation Point
when NO MORE solute can be dissolved at the given temperature
Factors affecting Solubility
Type of solvent, solute, and temperature
universal solvent
can dissolve so many things
Aqueous solution
means that what you are using can dissolve in water
Thermal Pollution
taking the cool water from the lake, cool the gases off, and eventually release the warm water back into the lake
Factors that affect the rate of dissolving
Temperature, size of particles, stirring
Viscosity
How quickly fluids flow
High Viscosity
The greater the friction or rubbing between particles
Low Viscosity
Fluids flow easily
