This alters the form of an object without changing its matter.
What is Physical Change
100
A solution of metal and another solid.
What is an Alloy.
100
A property that has two or more elements.
What is a Compound?
100
This substance tastes sour and burns if you touch it, turns blue litmus to red, and reacts with metals to make hydrogen gas.
What is an Acid?
100
The amount of matter in a certain volume of a substance.

What is a Base?
200
Any thing that has mass and takes up space.
What is Matter.
300
When a solid substance skips the liquid state of matter, going directly to a gas.
What is Sublimation.
300
The maximum amount of a solute that can dissolve in a solvent.
What is Solubility?
300
Provide two signs of a chemical change.
What is changes color, releases, forms tarnish, releases energy, forms a precipitate?
300
A special substance to identify acids and bases.
What is an Indicator?
300
A measure of the amount of matter in an object.
What is Mass?
400
Particles in the object start to move around faster pushing on each other causing the object to grow.
What is Thermal Expansion.
400
A mixture where the parts do not settle and looks cloudy and creamy.
What is a Colloid?
400
Carbon Dioxide and Sodium Acetate are two new substance formed by this chemical reaction.
What is Baking Soda and Vinegar?
400
This results in a higher freezing point, a lower boiling point, and increases density of water.
What is Salinity?
400
A measure of how much space an object takes up.
What is Volume?
500
When an object looses heat its particles slow down and the object shrinks.
What is Thermal Contraction.
500
A mixture used in one of the labs during science class.
