An example of colorless gas at room temperature is this. Plants also use it to make oxygen!
What is carbon dioxide?
100
Combined, a solvent and a solute form this.
What is a solution?
100
This is the smallest particles having the same properties of an element.
What is an atom?
100
When all matter is heated, the molecules do this. Just make sure they don't go over the speed limit!
What is it speeds up?
200
This is what gets dissolved in a solution.
What is the solute?
200
This cannot be broken down into simpler substances, as it is a basic building block of matter.
What is an element?
200
Solutions are formed by this process.
What is a solute getting dissolved by a solvent?
200
This pattern occurs when reading the periodic table from left to right.
What is an increase in atomic numbers?
200
When oxygen and iron combine, they create a reddish brown powder called iron oxide, or rust. It also creates an example of this change.
What is a chemical change?

An example of this process is dry ice changing into a gas.
What is sublimation?
400
A physical combination of two or more substances is called this.
What is a mixture?
400
This contains particles of matter that are in rapid motion and are widely spread out at room temperature. Hint: we breathe it out!
What is carbon dioxide?
