Question | Answer |
state of matter: definite volume + definite shape | solid |
state of matter: indefinite volume + indefinite shape | gas and plasma |
The amount of matter an object has | mass |
state of matter: definite volume + indefinite shape | liquid |
Property based on AMOUNT of substance | extensive |
a defined area (part of a sample) within a mixture | phase |
state of matter: most common | plasma |
the gas state of a substance that is a liquid or solid at room temperature | vapor |
Mixture that looks the same/uniform throughout; even distribution | homogeneous |
Property based on TYPE of substance | intensive |
The amount of space an object takes up | volume |
Mixture that looks different; uneven distribution | heterogeneous |
Mass divided by Volume calculates this intensive property | density |
anything that has mass and takes up space | matter |
can't be broken down by chemical means; usually written as a 1 or 2 letter abbreviation | element |
getting close to the true (expected) value | accuracy |
the exactness of a value Ex. 5.62 instead of just 5 | precision |
2 or more substances joined physically, not a fixed ratio | mixture |
can't be broken down chemically; usually a 1 or 2 letter symbol | element |
2 methods of separating parts of a mixture | filtration & distilation |
2 methods of separating parts of a compound | heat & electricity |
starting material in a chemical reaction | reactant |
speeds up a chemical reaction | catalyst/enzyme |
ending material in a chemical reaction ; get made | product |
absolute zero on this temperature scale | Kelvin |
0 is freezing and 100 is boiling on this temperature scale | Celsius |
this is not created or destroyed in a chemical or physical reaction | mass |
part of a solution that gets mixed in Ex: salt, sugar | solute |
part of a solution that does the mixing Ex: water | solvent |
add this to make a solution more concentrated | solute |
add this to make a solution more diluted | solvent |
