Chemistry Chapter 1 section 1

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

• biology

• physics

• astronomy

• chemistry

Research that is carried out for the sake of increasing knowledge, such as research into the properties of a substance, is considered to be

• applied research

• basic research

• technological development

• none of the above

The branch of chemistry called analytical chemistry most likely would be used in determining

• economic effects of a new substance

• chemical composition of a new substance

• effect of a chemical compound on living things

• uses of a particular metal

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

• organic chemistry

• biochemistry

• physical chemistry

• theoretical chemistry

A scientist is working to create a product that uses fiber optics. This is an example of

• applied research

• basic research

• technological development

• both applied and basic research

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 applied research is to

• find a solution to a particular problem

• produce new chemicals

• increase knowledge

• discover new technologies

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

• biochemistry

• physical chemistry

• analytical 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

• biochemistry

• physical chemistry

• inorganic chemistry

• theoretical chemistry

Chemistry is usually classified as a

• biological science

• computer science

• physical science

• social science
