Front

What are chemical properties?

Back

Chemical properties are characteristics of a substance that can only be observed when it undergoes a chemical change, resulting in the formation of a different substance.

Front

Define matter.

Back

Matter is anything that has mass and occupies space.

Front

What is an element?

Back

An element is a pure substance that cannot be separated into simpler substances by chemical or physical means.

List the three states of water in order of increasing kinetic energy.

Back

Ice, liquid, vapor.

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form or appearance of a substance without changing its chemical composition, while a chemical change results in the formation of new substances.

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout.

Front

What are the two main categories of properties of matter?

Back

The two main categories are physical properties and chemical properties.

Front

Give an example of a physical property.

Back

An example of a physical property is color, boiling point, or density.

Front

What happens to the kinetic energy of water as it changes from ice to vapor?

Back

The kinetic energy of water increases as it changes from ice (solid) to liquid and then to vapor (gas).

Front

What is the significance of the states of matter in understanding physical changes?

Back

The states of matter (solid, liquid, gas) help us understand how substances behave under different conditions and how they transition between states.
