Matter
Term | Definition |
---|---|
matter | any substance that has mass and takes up space |
atom | the smallest particle of an element that has the same chemical properties of its element |
element | a substance that can not be broken down into a simpler substance;an element consists of only one type of of atom |
density | refers to how tightly packed together the molecules of a substance are; the amount of mass in a given volume |
melting point | the temperature at which a substance will go through a phase change from a solid to a liquid |
boiling point | the temperature at which a substance will go from a liquid to a gas |
sublimation | the process of changing from a solid straight into a gas without going through the liquid phase |
mass | the amount of matter contained inside of an object |
volume | the amount of space taken up by an object, substance, or inside of a container |
solubility | the ability of a substance to dissolve |
solute | the substance that is being dissolved |
solvent | a solid, liquid, or gas that can dissolve another solid, liquid, or gas |
saturation | the point where a substance is holding as much solute as it possibly can |
phase change | transformations of a substance from one state of matter to another by heating or cooling |
subscript | in a chemical formula it indicates how many of that element are found in the molecule |
chemical properties | characteristics that can be observed during a chemical change Ex. Flammability, oxidation (rust) |
physical properties | observable characteristics that can be used to identify unknown substances ( boiling point, melting point, dew point, density, freezing point |
temperature | the movement of the molecules that creates hot or cold |
dew point (condensation point) | the temperature at which a gas turns into a liquid |
freezing point | the temperature at which a liquid turns into a solid |
solution | the substance created when one thing is dissolved into another |
