Solid: Has a definite shape and volume.
Liquid: Has an indefinite shape but a definite volume.
Gas: Has an indefinite shape and volume.
What are the characteristics of a solid, liquid, gas, in terms of shape and volume?
100
Changes the shape and size but not matter.
What is physical change?
100
matter.
What is chemical properties?
100
barely moving with very very low energy.
What are solid molecules doing?
100
Suspension, colloid, solution.
What are the different types of mixtures?
200
It is turning a substance from gas to solid.
What is sublimation?
200
no, fire does change matter.
Is fire a physical change?
200
Example: Radiation melting on ice cream
What is chemical change?
200
Bouncing all over the place like ninjas.
What are gas molecules doing?
200
It is a combination of a solid and a liquid. The solid dissolves in the liquid.
What is a suspension?
300
Any substance that has mass or volume.
What is the definition of matter?
300
the shape, the size.
What is a physical property?
300
yes, because they speed up and cause disruption.
Does the molecules speed and energy matter in a chemical change.
300
When you heat up a substance its molecules gain energy and move faster and more, therefore, the state of matter changes.
What is the kinetic theory of matter?
300
it is something that contains at least two substances that do not lose their chemical properties.
What is a mixture?
400
Shaving cream is around 80% liquid.
What is shaving cream, is it "mostly" a solid liquid or gas?
400
the difference is that you cannot change the matter.
What is the difference between chemical change and physical change?
400
fire.
what is an example of a substance that causes chemical change chemical change?
400
When you apply heat, the pressure increases.
What is Charles' law?
400
It is mixture of two or more elements combined. When they combine, they lose their original properties.
What is a compound.
500
A state of matter so hot that the electrons move freely.
What is plasma?
500
substance.
What is the difference between physical and chemical properties?
500
Yes, it would change the state and the properties of it.
would changing state of matter be a chemical change?
500
when you decrease the volume in of a container, the pressure gets grater.
What is Boyle's law?
500
they are similar because they are all related to each other but they are different because some are pure while others are not. Examples: A group of mixed rocks with different elements is different than a pure element that forms a rock by its self.
What are the similarities and differences between elements, compounds and mixtures? Can you provide an example of each?
