Matter and Properties

The study of the composition, structure, and properties of matter; the processes that matter undergoes; and the energy changes that accompany those processes best describes the science of

• Biology

• Earth Science

• Chemistry

• Astronomy

The branch of chemistry that involves the study of substances and processes occurring in living things is called

• theoretical chemistry

•   organic chemistry

• biochemistry

• physical chemistry

The branch of chemistry that deals with substances containing carbon is called

• Organic Chemistry

• Inorganic Chemistry

• Physical Chemistry

• Biochemistry

Using mathematical models and computer models to understand a chemical principle is an example of

• biochemistry

• analytical chemistry

• physical chemistry

• theoretical chemistry

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

• Physical Chemistry

• Biochemistry

• Theoretical Chemistry

• Inorganic Chemistry

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

• Biochemistry

• Inorganic Chemistry

• Organic Chemistry

• Analytical 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

The goal of basic research is to

• find a solution to a particular problem.

• produce new chemicals.

• increase knowledge

• discover new technologies.

A scientist is working on developing refrigerants that do not release chemicals that destroy the ozone layer. This is best described as an example of

• Basic Research

• Applied Research

• Technological Development

• None of the above

Technological applications often

• occur by accident

• degrade our quality of life.

• often overlap with basic and applied research.

• have little effect on our lives.
