What is attract?
When a liquid is cooled and changed to a solid.
What is freezing?
If a metal, glass, and wooden spoon were put into a pot of boiling water, why would the wooden spoon stay cooler the longest?
Because wood is a thermal insulator.
The process by which substances breakdown into small pieces and spread evenly in water.
What is dissolve?
True or false: a ping pong ball is less dense than water.
True (it will float on water)
Like poles ___________
What is repel?
When a liquid is heated and changed to a gas.

Physical State
What is physical state?
True or false: a glass marble will float on water.
False (it will sink because it is more dense than water)
True or false:
A magnet could be used to separate a mixture of pennies and iron filings.
True. Pennies are not magnetic, so they will be left behind after the magnet picks up the iron filings, which are magnetic.
When a gas is cooled and changed to a liquid.
What is condensation?
What is metal?
To separate a solution of water and salt, one must...
Boil the water until it all evaporates, the salt will be left behind.
Oil and water were poured into a beaker at the same time. Explain what the mixture will look like after 5 minutes.
The oil will be sitting on top of the water because it is less dense.
True or false: A magnet could be used to separate a mixture of paperclips and iron filings.
False. Both the paper clips and iron filings are magnetic.
In this state of matter, the molecules spread out and take the entire shape of the container they are in. This state of matter has mass, but not volume.
What is a gas?
