A team of scientists is working with living cells to determine how a certain enzyme functions within the cells. They are most likely working in the field of

• biochemistry.

• physical chemistry.

• inorganic chemistry.

• theoretical chemistry.

Two chemistry students are investigating the properties of quartz crystals. They are most likely studying in the field of

• biochemistry.

• physical chemistry.

• organic chemistry.

• inorganic chemistry.

The definition of a chemical is

• a toxic substance made in a laboratory.

• an unnatural material added to foods.

• any substance that has a definite composition.

• anything that has mass and takes up space.

An element is made of one type of

• molecule.

• atom.

• compound.

• mixture.

A compound is

• a substance that is composed of two or more elements that are chemically bonded.

• a molecule formed by atoms of the same element.

• another word for an atom.

• any substance that can be split apart.

Extensive properties

• include boiling point.

• do not depend on the amount of matter present.

• include volume and mass.

• all depend on the chemical composition of the matter present.

Which of the following is an intensive property of matter?

• volume
