What is matter?
Anything that has mass and takes up space
What are the 3 main states of matter?
solid, liquid, gas
What causes most changes in states of matter?
Changes in temperature.
What is all matter made of?
Tiny particles that are much too small to see
What do solids, liquids, and gases do when they are heated?
Expand
What is a mixture?
2 or more types of matter together in the same place
Is air matter?
Yes
Name one solid, one liquid, and one gas.
...
What is the name for the changed from solid to liquid?
melting
If all matter is made of particles, why are there different types of matter?
There are different types of particles.
What do solids, liquids, and gases do when they are cooled?
They contract
Name something that will dissolve in water.
Salt, sugar ...
Name some things that are not matter.
Time, temperature, sound, feelings...
Is the shape and volume of a solid fixed or changing?
Both are fixed
What is the name for a liquid becoming a gas at lower temperatures?
Evaporation
How are the particles arranged in a solid?
Packed close together, ordered, and they vibrate in place
Why do solids, liquids, and gases expand when they are heated?
The particles have more energy and move farther apart.
Name something that will not dissolve in water.
Sand, flour, dirt, a car ...
How do we know air is matter if we can't see it?
We can measure its mass and we can see it take up space.
Are the shape and volume of a liquid fixed or changing?
The shape is changing and the volume is fixed.
What is the name for a gas becoming a liquid?
Condensation
How are the particles arranged in a liquid.
They are very close together, but they can slide around each other and change position.

Why is it possible to compress (squish) a gas, but it is not possible to compress a solid or liquid?
The particles are farther apart.
Why does warm/hot air rise?
When the particles in the warm air move farther apart, the sam amount of matter takes up more space and becomes lighter than the air around it.
When something dissolves in water, we call the mixture a solution. How can we separate a solution?
Evaporate the water
