3 States of Matter
very close together
Do solids have a definite shape?
yes!
What is made up of matter?
EVERYTHING!
The temperature at which a solid turns into a liquid.
Melting Point
how are the molecules packed in liquids?
more loosely than solids
Do gasses have a definite shape?
no, they fill up the room they are in
What are the three phases of matter?
solid, liquid, gas
The temperature at which a liquid turns into a solid.
Freezing Point
how are the molecules in a gas packed?
very loosely
Do liquids have a definite shape?
no, they take shape of the container they are in
True or False: Solids, Liquids, and Gasses all have mass and take up space.
True
The temperature at which a liquid turns into a gas.
Boiling Point
Can a metal evaporate into a gas?
Yes, they just have a very high (hot) boiling point.
Which states of matter take the shape of their container.
Liquids and Gasses
What is the smallest form of an element?
atoms
The temperature at which a gas turns into a liquid.
Condensation Point
Can oxygen freeze into a solid?
Yes, it would just need high pressure and low/cold temperature.
What happens to particles as they heat up?
They separate and move around more.
What is the smallest form of a compound?
Molecule
The name for a solid turning directly into a gas, bypassing the liquid state.
Sublimation
