Molecules
Why do the molecules of oil and water not mix together?
The molecules are not attracted to eachother
Any matter or "stuff" that things are made of
Substance
What you can observe or measure about something that helps you describe it
Property (properties)
Matter is in EVERYTHING
True
If I freeze water, am I changing the state of its matter? Why?
Yes, when I freeze a liquid I am changing its state of matter into a solid.
If 2 or more liquids CAN mix together, what does that tell us about their attraction level?
They are VERY attracted to eachother
Anything that has mass and takes up space
Matter
A reaction or change in a substance that results in the creation of different substances
Chemical Change
Air has atoms in it
True. Air is made of molecules and molecules are made of atoms
What are the 3 states of Matter? Give me an example of each.
Solid (chair), liquid (water), gas (fart)
In our "coin" experiment, why were we able to drop 60 drops of water on the coin before the water fell off the coin?
The molecules have a high attraction
A way of describing how much "stuff" or matter is in an object
Mass
Something that scientists make to answer questions about the real world
Model
You can see a (1) water molecule with your eyes?
False
If I freeze or heat up a liquid, am I changing its mass?
No, the mass of matter stays the same
In our "coin" experiment, why were we only able to drop 20 drops of oil on the coin before the oil fell off the coin?
The molecules have a very low attraction
Combining 2 or more different substances together
Mixture
A tiny piece of matter that is too small to see
Atom
1,000,000 water molecules is enough molecules to fill up a glass with water?
False. It would take 8 octillion water molecules to fill of a glass full of water (1,000,000,000,000,000,000,000,000,000)
Molecules in a solid move how?
Molecules in a liquid move how?
Molecules in gas move how?
Solid, VERY slow - they are very slowly vibrating
Liquid - fast
Gas - VERY fast
If molecules reach a tempurature of absolute zero, what happens to them?
They stop moving
Use any of our 5 senses to gather information about something
Observe
A group of atoms joined together
Molecule
Different kinds of molecules have different shapes and sizes
True
Is it possible to seperate differne types of matter?
Yes
