Classification
Everything that has mass and takes up space.
Gases and liquids are classified as what?
Fluids
If this label is on a product or substance it means that it will easily catch fire.
Flammable
True or false: all particles are the same size
False
True or false: there are only 3 states of matter.
False. Plasma is another example.
Everything in the universe is either matter or what?
Energy
This fluid cannot be compressed, in other words, its volume doesn't change.
Liquid
If this label is on a product or substance it means that it can explode if it exposed to heat.
Explosive
This state of matter contains particles with the lowest energy state.
Solid
According to the classification of matter, cereal is an example of what kind of matter?
Heterogenous mixture
A glass of pop with ice is an example of what kind of mixture?
Heterogenous
Indefinite shape, indefinite volume
Gas
This WHMIS symbol with a fish and tree means you should take this precaution to protect wildlife, especially aquatic wildlife.
Don't dump/pour down the drain
Particles in this state of matter have the greatest space between them.
Gas
Why does water in Calgary boil at 96 degrees whereas it boils at 100 degrees in Vancouver?
Pressure. There is less pressure in Calgary because of our higher elevation, so it takes less thermal energy to change its state.
A solution is an example of this kind of mixture?
Homogenous
All fluids share these common properties, whether they are liquid or gas. Name both
They flow. Indefinite shape (take the shape of the container).
This WHMIS symbol shows a substance that burns a hand, meaning the substance inside is what?
Corrosive
Particles will begin to move faster if you add what?
Heat or energy
Water combines hydrogen and oxygen. Why is it a pure substance and not a mixture?
It is a compound, so there is still one type/kind of particle, H2O.
If the following sequence of letters represented particles, then this would be an example of what kind of mixture?
ababababababab
Solution or homogenous
Most fluids shrink or their volume decreases as they cool, most except this common fluid that is liquid at room temperature.
Water
You find this WHMIS symbol on boxes for needles in public.
Biohazard
The average kinetic energy of the particles of a substance is known as what?
Temperature
Why do fluids flow?
Particles of a fluid can move past and around each other.
