States of Matter
Question | Answer |
---|---|
4 states of matter | solid, liquid, gas and plasma |
solid | state in which matter has a definite shape and volume |
liquid | state in which matter takes the shape of its container and has a definite volume |
gas | state in which matter changes in both shape and volume |
pressure | the amount of force exerted on a given area |
Boyle's Law | for a fixed amount of gas at a constant temperature, the volume of a gas increases as its pressure decreases |
Charle's Law | for a fixed amount of gas at a constant pressure, the volume of a gas increases as its temperature increases |
plasma | state of matter that does not have a definite shape or volume and whose particles have broken apart |
change of state | the conversion of a substance from one physical form to another |
melting | the change of state from a solid to a liquid |
freezing | the change of state from a liquid to a solid |
vaporization | the chage of state from a liquid to a gas; includes boiling and evaporation |
boiling | vaporization that occurs throghout a liquid |
evaporation | vaporization that occurs at the surface of a liquid below its boiling point |
condensation | the change of state from a gas to a liquid |
sublimation | the change of state from a solid directly into a gas |
