Rust is an example of what kind of property?
Chemical
A state of matter with no definite shape of volume is a _______________________.
Gas
The amount of space an object takes up is _______________________.
Volume
How would you separate iron filings from sand?
Use a magnet
Which would ripen faster - an apple in a refrigerator or an apple at room temperature? Why?
The apple at room temp. because heats speeds up chemical change.
DOUBLE POINTS

A state of a matter with a definite volume but no definite shape is a ___________________________.
Liquid
All matter is made up of _________________________.
Atoms
What is a liquid mixture where on substance is mixed evenly throughout another substance is a _______________.
Solution
How would you create a control group in an experiment testing if color affects the amount of heat absorbed using glass jars of water covered with colored paper?

Painting a fence is what kind of property?
Physical
A state of matter with a definite shape and a definite volume is a ___________________.
Solid
The process by which water is changed from a liquid to a gas is _______________________.
Evaporation
True or False: To remove salt from a mixture of sand and salt, you could add water to dissolve the salt and then use a magnet to separate the salt from the mixture.
False - you would pour the mixture through a filter and the sand would not pass through. Then you would evaporate the water and the salt would remain.
TRIPLE POINTS
What is the rule that says that matter is neither created or destroyed during a change?
Conservation of Matter
TRIPLE POINTS
Digesting food is an example of what kind of property?
Chemical
_________________ is the ability for one thing to dissolve in another.
Solubility
TRIPLE POINTS
True or False: Atoms do not have mass.
False
In which liquid would sugar dissolve faster - ice tea or hot tea? Why?
Hot tea because heat speeds up solubility.
DOUBLE POINTS
True or False: A chemical change can be reversed.
False
