This phase of matter has definite shape and volume.
What is solid?
The measure of the amount of matter within an object.
What is mass?
This type of change to matter occurs when the size, shape, or state of matter changes.
What is physical change?
When a solid turns into a liquid.
What is melting?
These two names are used to describe substances and chemicals, especially liquids, and ranges from 0 to 14.
What are acids and bases?
This phase of matter has indefinite shape and indefinite volume.
What is gas?
The amount of space and object takes up.
What is volume?
This type of change cannot be reversed.
What is chemical change?
When a liquid turns into a gas.
What is evaporation?
This type of mixture can be separated into its seen separate parts.
What is a heterogeneous mixture?
This phase of matter has indefinite shape and definite volume.
What is liquid?
This measures the amount of matter in an object and the pull of gravity on it.
What is weight?
The name of the substance that is produced through a reaction.
What is a product?
What are 3 ways to tell that a chemical change has occurred?

What are materials?
Rank the phases of matter based on how fast the molecules within it moves, with 1 being the slowest.
1. solid
2. liquid
3. gas
This is the ability to dissolve in water.
What is solubility?

When a liquid becomes a solid.
What is freezing?
What is the speed at which a reactant turns into a product?
What is reaction rate?
Rank the phases of matter based on how dense the molecules are within, with 1 being the most dense.
1. Solid
2. Liquid
3. Gas
This measures the amount of mass within a given volume.
What is density?
What are 3 of the 5 different types of chemical reactions?
combustion, chain reaction, photochemical, decomposition, synthesis
This says that matter can't be created or destroyed and remains the same amount before and after reactions.
