States Of Matter
What are the 3 states of matter?
Solids, Liquids and Gases.
What is a Homogeneous mixture?
A mixture with components that cannot be easily identified.
List the parts of an atom.
What is a solvent?
A solvent is a substance that is doing the dissolving.
Why is separating mixtures important?
It is importants because oil industries, nuclear power industries, recycling industries, water purification industries because they all use separating mixtures.
What is the process of a gas turning into a liquid called?
Condensation.
What is a Heterogeneous mixture?
A mixture with easily identified components.
Are the particles in a solid always moving?
Yes, the particles indeed are moving, but the movements are so small you can't see them.
What is a solute?
A solute is the substance that is dissolved in the solution.
How do you separate rocks from sand?
By sifting the rocks and sand.
What is the process of a gas turning into a solid called?
Deposition.
What is the difference between a homogeneous mixture and heterogeneous mixture?
A heterogeneous mixture components can be easily identified while a homogeneous mixtures components cannot be easily identified.
They're scattered around and moving freely.
How can you tell if something is saturated or not?
If something is saturated, a solute cannot dissolve anymore in it and if something is not saturated, more solute can dissolve in it.
How do you purify water?
Use filters to remove bacteria and anomalous objects from the water.
How to you turn a liquid into a gas and what is the process called?
Heat the liquid up. It is called evaporation.
Give 3 examples of a heterogeneous mixture.
pizza, burger, and cookie dough
Should heat be taken or added if you want to turn a gas into a liquid?
You should let the gas cool down.
List the 3 major factors that influence the rate of dissolving.
1. Temperature
2. Movement
3. Size
How do you separate uranium from it's ore?
Crush the uranium ore, then you dissolve it in a solution so you can remove the rock particles using a sieve.
NAME ALL OF THE PROCESSES OF CHANGING STATES.
GIVE 5 EXAMPLES OF A HOMOGENEOUS MIXTURE.
tea, coffee, lemonade, milk, and hot chocolate
LIST ALL THE 5 MAJOR POINTS OF THE PARTICLE THEORY.
2. The particles are always moving.
3. There is space between all particles.
4. Adding heat makes particles move faster.
5. All particles in a pure substance are the same.
Different substances are made up of different particles.
What is a strategy you can use to tell if a solid is present in a liquid?
see if it changes colour and taste it but only if it is safe.
LIST ALL THE METHODS TO SEPARATING MIXTURES.
1. Evaporation
2. Sifting
3. Filtration
4. Distillation
5. Magnetism
