Solid
What can you tell me about a solids shape and volume?
Double Points: Explain your answer
Its fixed, meaning it doesnt take the shape of its container but takes up the same amount of space no matter where it is
Do liquids have a fixed shape or do they take the shape of their container?
Shape of their container
Do gases have a fixed shape?
Bonus: Explain
No, they fill their container
What are the three main parts of an atom?
proton, neutron, electron
What determines what element an atom is
Number of protons
Are particles packed tightly together or far apart?
Packed tightly together
Do liquids have a fixed volume?
Bonus: explain what this means
Yes, this means that even though they take the shape of the container, they always take up the same amount of space unless the amount of liquid changes
Do gases have a fixed volume?
Bonus: Explain
No, they expand to fill all available space
What is the negative part of an atom
electron
I have:
Who am I?
Magnesium
Do particles move freely or vibrate in place?
Vibrate in place
Are particles in a liquid able to move past each other or are they locked in place?
They move past each other
Are gas particles close together or far apart?
Far apart
Where are the protons and neutrons found
In the nucleus
I have:
Who am I?
Aluminum
Name a solid that can flow
Bonus: Explain why it can flow
sand, salt, sugar because the individual solids are so small that when poured it looks like a liquid
What has to happen for a liquid to become a solid?
Bonus: Gas?
Take energy away, add energy
How do gas particles move compared to solids and liquids?
Hint: 3 things
They move freely, quickly, and in all directions
Where is most of the mass found?
Bonus: what determines the mass?
The Nucleus, protons and neutrons
I have:
Who am I?
Phosphorus
Why are solids harder than liquids or gasses?
Because their particles are already tightly packed with very little empty space.
Why are liquids harder to compress than gases but easier to compress than solids?
The particles are close together but still have space to move
Why are gases easy to compress?
There is a lot of space between particles so its easy to squish more into a container
Describe the relationship between protons and electrons
Bonus: Protons and protons, electrons and electrons
Protons and electrons have different charges. Opposites attract. Protons are positive and are attracted to negative electrons. Protons push away from other protons and electrons push away from other electrons.
I have:
