Term |
Definition
|
| Boiling Point | The temperature at which a material boils at normal atmospheric pressure. |
| Melting Point | For pure substances, the temperature at which transition from solid to liquid form is complete. For mixtures, such as waxes, the temperature at which the transition begins. |
| Pour Point | The lowest temperature at which a liquid will flow or pour. |
| Vapor Pressure | The pressure of saturated vapor above liquids or solids at the stated pressure. |
| Viscosity | Internal resistance to flow exhibited by a fluid. |
