acids and bases
100
Everything is made of this.
What is matter?
100

As a substance absorbs thermal energy (heat), its particles move this way.

What is faster (or spreading further apart)?

100
Anything that takes up space, has mass, and has properties you can observe and describe.
What is matter?
100

To calculate density, you divide a substance's mass by this measurement.

 What is volume?

100

Acids typically taste sour, while basic solutions (like soap water) typically have this physical feeling.

What is slippery

200
It is how much matter is in an object.
What is mass?
200

This term describes the measurement of the average kinetic energy (speed) of the particles in a substance.

What is temperature?

200
A form of matter that takes up a definite amount of space and has NO definite shape.
What is liquid?
200

Pure liquid water has a density of exactly this value.

What is 1 g/ml or 1 g/cm 3 

200

Pure distilled water sits right in the middle of the pH scale with this exact number.

pH 7

300
Size, shape, color, texture, smell!
What are properties? or What are examples of properties?
300

Water droplets forming on the outside of a cold soda can on a hot summer day is an example of this phase change.

What is condensation?

300
A form of matter that DOES NOT take up a definite amount of space and has NO definite shape.
What is a gas?
300

If an unknown solid has a density of 0.6 g/cm3, it will do this when dropped into a bowl of pure water.

what is float ?

300

Any solution that falls between 0 and 6 on the pH scale is classified as this type of substance.

Acid

400
Solid, liquid, gas
What are the three states or groups of matter?
400

According to particle theory, these two things happen to a substance's particles as it absorbs thermal energy and heats up.

What is they move faster and spread further apart?

400

Flammability, reactivity with water, and the ability to rust are all examples of this type of property, which describes how a substance can transform into a completely new substance.

chemical property?

400

When liquids of different densities are poured into a cylinder, the liquid with the lowest density will end up in this position.

What is at the top?

400

Acids have a pH below 7 because they contain a very high concentration of these positively charged particles.

What are hydrogen ions ($\text{H}^+$)?

500
A form of matter that has a definite shape and takes up a definite amount of space.
What is a solid?
500

Dry ice changing directly from a solid into a carbon dioxide gas without turning into a liquid first is an example of this phase change.

What is sublimation?

500

Food coloring spreads much faster in a beaker of boiling water than in ice water because the water particles have more of this specific type of energy.

What is kinetic energy?

500

A stone has a mass of 45 g and occupies a volume of 15 ml. This is the exact density of the stone.

3 g/ml

500

This is the scientific name for the reaction that occurs when an acid and a base are mixed together in equal amounts, creating water and salt.

What is neutralization?
