SOLID/LIQUID/GAS
MATTER
HOT & COLD
ANYTHING ELSE
100
Burning paper, like your homework, is an example of this kind of change.
What is a chemical change?
100
It's the state of matter seen in the middle:
What is a liquid?
100
All matter is made of tiny particles called this.
What are atoms?
100
Removing heat from a liquid will eventually do this to it.
What is freezing?
100
Doing this well will prevent heat (energy) from escaping or entering something.
What is insulating?
200
Temperature change, bubble formation, or precipitate formation would be signs of this type of change.
What is a chemical change?
200
It is when a substance changes from a gas to a solid.
What is deposition?
200
There are over 100 different types of atoms. Each type of atom is called this.
What are elements?
200
When a cup of hot water is sitting in an air conditioned room, then the energy is traveling in this direction.
What is away from the cup // What is away from the hot water?
200
If a reaction ended with a mass of 200 grams, then the reaction must of started with this amount.
What is 200 grams?
300
When you mix sugar with water, the sugar looks like it disappears! But it really is dissolved in the water, which is an example of this type of change.
What is a physical change?
300
This phase of matter has particles that vibrate in place. The particles do not move past each other.
What is solid?
300
A substance that is made up of two or more types of atoms is called this.
What is a compound?
300
Adding energy to a liquid can cause it to turn into this phase of matter.
What is a gas?
300
For example, water's is H2O, carbon dioxide's is CO2, and table salt's is NaCl.
What is a chemical formula?
400
This type of change would look like this:
AA + BB --> AA + BB
What is a physical change?
400
This state of matter has particles that can smoothly move past each other
What is liquid?
400
Matter is defined as anything that has mass and takes this up.
What is space?
400
Temperature is related to this measurement of a substance.
What is kinetic energy?
400
If (5 mL of A)+ (10 mL of B) --> 10 mL of gas, and
(10 mL of A) + (10 mL of B) --> 10 mL of gas, then B is considered to be this.
What is a limiting factor?
500
When a chemical reaction occurs, the atoms do this.
What is rearrange//What is create new substances?
500
This type of matter does not have a definite volume nor definite shape.
What is a gas?
500
When matter is mixed together, it can chemically change. However, this measurement (before and after a reaction) will never change, according to the Conservation of Matter.
What is mass?
500
A 25 degree solid bar of gold sitting out on the table would have this in common with the 25 degree air surrounding it.
What is the same temperature // What is the same kinetic energy?
500
If an air-filled balloon were put in the freezer, we would expect this balloon to do this, due to a drop in temperature.
What is contract?
