The 4 States of Matter
Term | Definition |
---|---|
Solids | have a definate shape and volume. |
Liquids | have a definate volume but not shape. |
Gases | have no definate shape or volume. |
Surface Tension | force on liquid surface |
Viscosity | resistence of gas and liquid flow |
Temperature | how hot or cold something is |
Volume | how much space an object takes up |
Pressure | the amount of force on something |
Boyle's Law | For a fixed amount of an ideal gas kept at a fixed temperature, P [pressure] and V [volume] are inversely proportional (while one doubles, the other halves). |
Charles's Law | At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale (i.e. the gas expands as the temperature increases). |
Condensation | Gas to liquid |
Boiling | when a liquid is bubbly due to heat |
Changes of State | 1 phys. state to another |
Sublimeation | Solid to gas |
Evaporation | Liquid to gas |
Melting | Solid to liquid |
