A | B |
solid, liquid, gas, plasma | 4 phases of matter |
solid | definite shape and volume |
amorphous | solids that lose shape under certain conditions |
glass, wax, tar | examples of amorphous solids |
crystals | solids arranged in a regular repeating pattern |
liquid | no definite shape but a definite volume |
viscosity | resistance of liquid to flow |
gas | no definite shape or volume |
Boyles law | volume of a mixed amount of gas varies inversely with the pressure of the gas. Ex. if pressure increases, volume decreases |
Charle's law | law of gasses - if volume increases, temperature increases |
melting | solid to liquid |
melting point | temperature at which a solid changes to liquid |
freezing | liquid to a solid |
freezing point | temperature at which a liquid changes to a solid |
vaporization | liquid to a gas |
evaporation | vaporization taking place at surface of a liquid |
condensation | gas to a liquid |
sublimation | solid to a gas |
chemical property | property that describes how a substance changes into a new substance |
flammability | chemical property that describes the ability to burn |
physical | color, shape, hardness, and density are all examples of _________ properties |
plasma | high energy phase of matter not naturally found on Earth, sun contains this |
loss or gain of heat energy | phase changes are accompanied by 2 things |
boiling | vaporization throughout a liquid |
boiling point | related to the air pressure above the liquid |
chemical reaction | another name for a chemical change |
inverse | one factor increases while the other decreases |
deposition | gas to a solid |
vaporization | Is vaporization or evaporation considered a phase change? |
stability | chemical property that descrbes the ability of a substance to ot change |
malleability | physical propert that describes how well an object can be hammered into a sheet. |
lost | Energy is ______ when going from a liquid to a solid |
gas laws | describes the behavior of gases |
pressure, volume, temperature | gas laws involve changes in what 3 things |
