A ___________ is 2 or more substances that are not Chemically combined.
A Mixture
100
In a(n) ____________ Change, atoms rearrange and new substances form
Chemical Change
100
This state of matter has a definite shape and a definite volume.
Solid
100
What is Energy?
The ability to do work or cause change.
100
What is a Fluid?
A substance that flows (its molecules move easily past one another)
200
What is a Compound?
A pure substance that is made of 2 or more elements chemically combined in a set ratio
200
Breaking a Pencil or Bending a Pen are examples of __________ Changes.
Physical Changes
200
This state of matter takes the shape of its container, but has a set volume.
Liquid
200
_____________ energy is stored in the bonds between atoms.
Chemical Energy
200
What happens to the Volume of a Gas when the Pressure is increased at constant Temperature?
It decreases
300
True or False: Mixtures are Easy to separate into their components.
True
300
A(n) _____________ change is any change where energy is released.
Exothermic Change
300
This state of matter has the least energy.
Solid
300
X-rays, Light, and Radio Waves are examples of _____________.
Electromagnetic Energy
300
What is the law of Conservation of matter?
Matter is never created or destroyed by any Physical or Chemical Change
400
Flammability, the Ability to Rust, and The ability to react are examples of ______________.
Chemical Properties
400
The opposite of condensation is ______________.
Vaporization
400
This state of matter changes its volume the most easily.
Gas
400
What is the difference between Temperature and Thermal Energy?
Temperature is the average speed of the molecules in an object, Thermal Energy is the total energy of all of the molecules in an object.
400
How is the process of Water Freezing different than most other substances?
Water expands as it freezes, which means that ice has a higher volume than water
500
True or False, compounds have similar properties to the elements that make them up.
False
500
Water freezing into Ice is what kind of change? (Be as SPECIFIC as possible!)
Physical and Exothermic
500
What is the difference between an amorphous and a crystalline Solid?
Crystalline Solids have molecules that are arranged in set, repeating patterns. Amorphous solids have molecules that are not arranged in a pattern, and do not have a set melting point.
500
You add energy to water that is 90 degrees Celsius. What happens next?
The molecules speed up and temperature increases until it reaches 100 Celsius, at which point vaporization begins. The molecules spread out and temperature will stay the same until all of the water is vaporized, at which point it will begin to rise again.

Describe the graph of either Charles' Law or Boyle's Law (you must include what goes on each axis)
Charles' Law: Temperature (x-axis) vs. Volume (y-axis) = straight line up to the right (directly proportional) Boyle's Law: Pressure (x-axis) vs. Volume (y-axis) = curve down to the right (inversely proportional)
