MATTER
Matter is made up of tiny________that are moving?
particles
When two or more different substances (or materials) are combined the result is a_________-
mixture
mixing to combine a solid and a liquid
Substances will dissolve faster in warmer water than in colder water
Temperature
Things like oil, plastic, tyres, tins, glass and sewage waste are bad for the water and people using the water
insoluble substances
Particles are packed together
solid
This is best use for mixtures with large solids such as coins, beans, peanuts or sweets.
Hand sorting
uses heat to convert one solid into a liquid
melting
The speed at which a solute dissolves
Rates of dissolving
Never throw waste into a river or on the ground.
Preventing water pollution
Matter in this state is able to flow. The substance will take on the shape of the container it is in.
Liquid
to separate the smaller solids from the larger ones
Sieving
The liquid in which a solute dissolves is called
Solvent
The larger the grain______
the slower the rate of dissolving will be
This means it is very difficult to know if they are in water or not.
Soluble substances
There is a lot of space between the particles. 7 The particles move in all directions.
Gas
letting the mixture sit and waiting for it to separate on its own
Settling
Solids that can dissolve are called
Solutes
A large solute will take longer to dissolve
Grain size
living creatures that cannot be seen with the naked eye that pollute water
Germs
Particles move faster when we add what to them.
heat
Some mixtures are separated by pouring them through paper or other materials.
Filtering
when a solution has no more space for any more particles of the solute.
Saturated
Agitating the solution is also know as_____
stirring or shaking
shallow body of water with plants such as reeds.
