This property of matter describes the ability of a substance to undergo changes in identity.
What is chemical property?
800
The process matter undergoes when it turns from a gas to a liquid.
What is condensation?
800
When two liquids combine and form a solid substance.
What is a precipitate?
1200
The state where particles move quickly, spread out and take up all avaialable space, and it can cange both space and volume.
What is gas.
1200

1200
The process matter undergoes when it turns from a gas to a solid.
What is deposition?
1200
A chemical reaction that causes heat to be produced.
What is an exothermic reaction?
1600
This state of matter is made when particles collide with enough energy to break into charged particles.
What is plasma?
1600
Sometimes called a solution, this type of mixture contains very small particles where the particles are dissoled in a liquid, but not chemically combined.
What is a homogeneous mixture?
1600
This chemical property describes how much a substance can damage a cell, organ or organism.
What is toxicity?
1600
The process matter undergoes when it turns from a solid to a gas.

1600
When energy is absorbed in a chemical reaction.
What is an endothermic reaction?
2000
This is the amount of atoms an object contains.
What is mass?
2000
A mixture where particles don't dissolve and may or may not settle out.
What is a heterogeneous mixture?
2000

What is oxidation?
2000
To cause a solid to melt into a liquid you would have to do this.
What is increase heat energy?
2000
When observing a chemical reaction, the producation of bubbles is evidence of this chemical change.
