Vapor pressure
| Oil glossary |
- Pressure of a confined vapor in equilibrium with its liquid at specified temperature thus, a measure of a liquid`s volatility.
- Давление пара
- The component of the total pressure which is caused by the presence of a vapor, as, for example, by the presence of water vapor in air.
- The measure of a liquid’s volatility. the higher the pressure at a standard test temperature, the more volatile the sample, and the more readily it will evaporate.
- Measure of the volatility of a liquid at specified temperatures and pressures (or vacuum).
- Pressure exerted by the vapor of a liquid when in equilibrium in a closed system at the interface with a condensed phase (solid or liquid) at a specified temperature. these limiting pressures can restrict the levels of pressurization of enclosures with these tracer gases during pressure leak testing and can also limit the vacuum obtainable in presence of these liquids (for example, water or solvents).

Equilibrium, английский
- Равновесие
- The state of being equally balanced; a state of a body in which the forces acting on it are equally balanced.
- A state of balance
- Равновесие, равновесное состояние ~ of forces равновесие сил
- Literally balance, here balance of forces acting on each other. in a static equilibrium forces compensate each other so that the system is motionless, e.g., a scale at rest. if forces do not compensate each other fully at one instant in time, a system moves until it encounters higher-order constraints, e.g, after starting an engine, it accelerates to a point at which energy supply and work load plus friction are again in balance. in such a dynamic equilibrium, forces complement each other dynamically so that the system`s behavior is repetitive, predictable, does not generate new states and the trajectory follows a regular cycle. e.g., mass production at a well-worked out assembly line, sterotypical conversation within a 28 family, routine administrative procedures. a system may have several distinct equilibria (->polystability). a system in equilibrium conveys no information. one important equilibrium property is stability. homeostasis is a process of interaction favouring an equilibrium.
- The stable state of the system. see: attractor.
- A state of balance in which there is no tendency for change. see disequilibrium.

- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).

- The property of a liquid that defines its evaporation characteristics. of two liquids, the more volatile will boil at a lower temperature and will evaporate faster when both liquids are at the same temperature. the volatility of petroleum products can be evaluated by tests for flash point, vapor pressure, distillation and evaporation rate.
