Particle & Matter
Particles are?
What is Building blocks of the world?
This is used to take out a solid from a liquid
What is Filtration?
A pure substance made of only one kind of particle is called this.
What is an element?
Name the solute and the solvent in saltwater.
What is Solute is salt. solvent is water
Metals like iron, copper, and gold come from?
What is Minerals/ores from the Earth?
How many points of particle theory are there?
What is five or six?
This uses heat to take out a liquid from a solid
What is Evaporation?
A mixture where you can see the different parts of the mixture is called...
What is a mechanical and, or heterogeneous mixture?
A solution that can still dissolve more solute is called?
What is Unsaturated?
The rock that has rare materials mixed with other common materials is called?
What is Ore?
what happens when particles are heated up?
What is they speed up?
This thing pulls apart different liquids by using their different boiling temperatures.
What is Distillation?
A type of mixture where everything looks the same.
What is A homogeneous mixture?
A solution that has dissolved as much solute as it can is called?
What is Saturated?
This thing is used alot to purify metals after they are mined.
What is Smelting?
Why can gases be squished, but solids can't?
What is there is space between particles in gases, but not a lot in solids?
You would use this to separate iron filings from sand.
What is Magnetism?
Explain why saltwater is a mixture and not a pure substance.
What is Because it has water and salt particles that are in it.
Explain why stirring helps a solute dissolve faster.
What is stirring makes particles mix in with each other.
Describe one way mining waste can harm the environment.
What is waste from mining?
Why do gas particles have more space than liquids?
What is Gas particles move faster and farther away from each other, so they spread out faster.
Explain why distillation can make pure water from dirty or salty water.
What is Heat up the water and kill the germs etc in the water?
Compare a mechanical mixture and a solution using the particle theory.
What is in a mechanical mixture, things stay separate and you can see them. In a solution, things are equaly mixed and look the same.
Explain why warm water dissolves sugar faster than cold water.
What is hot water has faster‑moving particles, so they speed up unlike cold water?
how does mining create water pollution?
What is water that can come out of mine cracks that is acidic and can be mixed with zinc or copper etc, from the mines.
