| Question | Answer |
|---|---|
| Chemistry | The study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes |
| Organic Chemistry | The study of most carbon-containing compounds |
| Inorganic Chemistry | Study of non-organic substances, many of which have organic fragments bonded to metal |
| Analytical Chemistry | The identification of the components and composition of materials |
| Biochemistry | The study of substances and processes occurring in living things |
| Theoretical Chemistry | The use of mathematics and computers to understand the principals behind observed chemical behavior and to design and predict the properties of new compounds |
| Chemical | Any substance that has a definite composition |
| Basic Research | Carried out for the sake of increasing knowledge |
| Applied Research | Generally carried out to solve a problem |
| Technological Development | Typically involves the production and use of products that improve our quality of life |
| Volume | The amount of three dimensional space an object occupies |
| Mass | Measure of the amount of water |
| Matter | Anything that has mass and takes up space |
| Atoms | The smallest unit of an element that maintains the chemical identity of that element |
| Elements | Pure substances that can't be broken down into simpler, stable substances. Each is made of atoms of two or more elements that are chemically bonded |
| Extensive Properties | Depend on amount of matter present |
| Intensive Properties | Do not depend on amount of matter present |
| Change of state | Physical change of a substance from one state to another |
| States of matter | Solid state, liquid state, gas state, plasma |
| Solid state | Matter has a definite volume and definite shape |
| Liquid state | Matter has definite volume but indefinite shape |
| Gas state | Matter has neither definite volume or shape |
| Plasma | High-temperature physical state of matter in which atoms lose most of their electrons, particles that make up atoms |
| Chemical Property | Substance's ability to change |
| Chemical Change or Reaction | Change when one or more substances convert into different substances |
| Reactants | Substances that react in a chemical change |
| Products | Substances that are formed by the chemical change |
| Energy | .Always involved when physical or chemical changes occur .Can be in various forms (Ex: Heat, Light) .Can be absorbed or released in a change, it is not created nor destroyed .Law of conservation of energy |
| Mixture | A blend of two or more kinds of matter, each of which retains its own identity and properties |
| Pure substance | Has a fixed composition |
