Unit 1 LO1: What is chemistry?

matter

anything that has mass and occupies space

matter

anything that has mass and volume - everything but energy

analytical chemistry

area of study that focuses on the composition of matter

physical chemistry

area that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change

energy

capacity to do work or produce heat

extensive property

depends on amount of matter

intensive property

depends on type of matter, used to classify matter

solution ex. lemonade

evenly distributed throughout

matter flow chart

matter separates into mixture and substance, mixture splits into heterogeneous mixture and solution, substance splits into compound and element

chemical property aka chemical reaction

observe property by changing the matter

physical property ex. color

observe without changing the matter

biochemistry

study of processes that take place in organisms

chemistry

study of the composition of matter and the changes that matter undergoes

compound ex. H20

substance that can be broken down chemically or substance made from two or more elements

element

substance that can't be broken down chemically

organic chemistry

the study of all chemicals containing carbon

inorganic chemistry

the study of all chemicals that, in general, do not contain carbon

substance

type of matter that is chemically combined

mixture

type of matter that is physically combined

heterogeneous mixture ex. air

unevenly distributed throughout
