states of matter
|
The physical forms in which a substance can exist.
|
|
solid
|
The state in which matter has a definite shape and volume.
|
|
liquid
|
The state in which matter takes the shape of its container and has a definite volume.
|
|
gas
|
The state in which matter changes in both shape and volume.
|
|
pressure
|
The amount of force exerted on a given area.
|
|
Boyle's law
|
This law states that for a fixed amount of gas at a constant temperature, the volume of a gas increases as its pressure decreases.
|
|
Charles's law
|
This law states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as its temperature increases.
|
|
plasma
|
This is the state of matter that does not have a definite shape or volume and whose particles have broken apart.
|
|
change of state
|
This is the conversion of a substance from one physical form to another.
|
|
melting
|
This is the change of state from a solid to a liquid.
|
|
melting point
|
This is the temperature at which a substance changes from a solid to a liquid.
|
|
endothermic
|
energy is absorbed
|
|
freezing
|
The change of state from a liquid to a solid.
|
|
freezing point
|
The temperature at which a liquid changes into a solid.
|
|
exothermic
|
energy is removed or released
|
|
vaporization
|
The change of state from a liquid to a gas.
|
|
boiling
|
This is vaporization that occurs throughout a liquid.
|
|
evaporation
|
This is vaporization that occurs at the surface of a liquid below its boiling point.
|
|
