bonus/extra questions
100
All matter is made up of tiny particles called?
Atoms
100
What does water do when its put in a container?
It takes up the shape of the container.
100
What state of matter always has the same volume but can change shape?
Liquid.
100
How can you tell if something is a mixture?
You can see all the diffrent particals.
100
how many particles do compounds have?
they have 2 or more particles that are chemically bonded together.
200
Do particles ever stop moving?
No, particles are always moving.
200
What does gas do when its put in a container? (write two answers)
It takes up the shape and volume.
200
What is it called when a liquid turns into a gas?
Boiling/evaporation
200
What are 3 examples of a pure substance, and 3 examples of a mixture?
Elements only have one partical and compounds have 2 or more partical that are chemically bonded together
Some examples of Pure substances are : Gold, Oxygen,Salt,Sugar,Water.
Some examples of Mixtures are: Pizza,ketchup,Sand,Soil,etc.
200
what can you do to make matter change states?
adding or removing states
300
The particles in gas have a lot of empty spaces between them. What would happen to the empty spaces when it becomes a solid?
The particals would be packed together more tightly but there would still be empty spaces.
300
What do the particles of a banana look like when in a container? (write a word answer and draw what it looks like.)
They are tightly packed together, like in the picture.
300
What is evaporation?
It is when a liquid turns into a gas.
300
What makes something a mechanial mixture?
Something that has more then two particals that you can see.
300
true or false the particals in cold water have more energy than in hot water?
false
400
What happens to particles when you add heat to them?
They speed up and spread apart.
400
What state of matter is in a balloon?
Gas is in a balloon.
400
What is it called when a solid becomes a gas?
Sublimation

400
How many pure substances are in a solution?
2 or more.
400
To make matter change states you add or take away what?
you add or take away heat energy
500
What are particles attracted to?
Each other (particals).
500
Do the atoms in a table vibrate true or false?
True
500
What is it called when a gas becomes a solid?
Deposition
500
What is the diffrence between elements and compounds?
Elements only have one partical and compounds have 2 or more partical that are chemically bonded together
500
how do you make particals move faster?
you have to increase energy (the temperature).
