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 |
