Anything that has mass and takes up space - Answer-Matter A set of controlled observations that test a hypothesis - Answer-Experiment A measure that reflects the amount of matter - Answer-Mass A characteristic of matter that can be observed or measured without changing the sample's composition. Example: density, color, taste, hardness, and melting point - Answer-Physical property A form of matter that flows, has constant volume, and takes the shape of its container. - AnswerLiquid One that has a uniform composition throughout and always has a single phase; also called a solution - Answer-Homogeneous mixture A chemical combination of two or more different elements; can be broken down into simpler substances by chemical means and has properties different from those of its component elements - Answer-Compound The metric unit for volume equal to one cubic decimeter - Answer-liter The metric unit of temperature measurement. - Answer-Celsius the value measured in the lab - Answer-Experimental value The study of matter and the changes that it undergoes - Answer-Chemistry In an experiment, the variable that the experimenter plans to change - Answer-Independent variable the amount of 3-dimensional space occupied by an object - Answer-VolumeThe ability or inability of a substance to combine with or change into one or more new substances - Answer-Chemical property A form of matter that flows to conform to the shape of its container, fills the container"s entire volume, and is easily compressed - Answer-gas A uniform mixture that can contain solids, liquids, or gases; also called a homogeneous mixture - Answer-Solution the principle stating that matter is not created or destroyed during a chemical reaction - AnswerConservation of mass The difference between an experimental value and an accepted value - Answer-Error The SI base unit for mass - Answer-Kilogram The SI base unit of temperature - Answer-Kelvin A systematic approach used in scientific study; an organized process used by scientists to do research and to verity the work of others - Answer-Scientific method
