Phases
The phase where atoms are tightly packed but still vibrate.
Solid
H2O is this
Water (or a molecule!)
The addition or taking away of this will cause a phase of matter to change
Energy! (heat energy!)
A mixture where one substance dissolves into another.
solution
This has mass and takes up space.
matter
The phase where matter has no shape or volume an particles are spread apart.
Gas
The smallest part of matter
Atoms
If temperature is increased an ice cube will change to
a liquid (water)
A combination of 2 or more substances that DO NOT lose their characteristics.
mixture
The amount of matter in a solid, liquid or gas
mass
The phase of matter that takes the shape of the container it is in, but has a definite volume (size).
Liquid
Draw the atoms in a gas
The drawing should show atoms spread apart!
Changing from gas, to liquid, to solid happens when we ______________heat
decrease or take away
When making a solution, adding this can speed up the dissolving process.
heat
This measure changes and is based on gravitational pull
weight
The phase that has a shape and doesn't change
Solid
When a matter changes from a solid to a liquid to a gas, does the mass change?
No!
If a 50 gram ice cube melts, what is the mass of the water left behind?
50 grams
Lucky Charms--mixture or solution?
mixture!
What is the definition of volume?
The amount of space something takes up!
Atoms in this move the fastest and are spaced very far apart
Gas
TRUE or FALSE: All mixtures are solutions.
What is false?
As temperature increases, the atoms of a solid will move_____________ and be far ___________
faster/apart
Chocolate milk - mixture or solution
solution
Draw the atoms in each state of matter!
The atoms in a solid should be close, the ones in a liquid moving further away from each other!, and the ones in a gas very far away!
