Parent topics
- Physics [r]: The study of forces and energies in space and time. [e]
- Chemistry [r]: The science of matter, or of the electrical or electrostatical interactions of matter. [e]
- Engineering [r]: a branch of engineering that uses chemistry, biology, physics, and math to solve problems involving fuel, drugs, food, and many other products. [e]
- Thermodynamics [r]: The statistical description of the properties of molecular systems [e]
Subtopics
- Gas compressor [r]: A machine that increases the pressure of a gas by reducing its volume. [e]
- Partial pressure [r]: The pressure which each gas in a gas mixture would have if it alone occupied the same volume at the same temperature. [e]
- Vacuum (science) [r]: A realizable vacuum with a gaseous pressure that is much less than atmospheric. [e]
- Vapor pressure [r]: The pressure of a vapor in equilibrium with its liquid or solid phase. [e]
Units
- Atmosphere (unit) [r]: A unit of pressure measurement (symbol: atm) defined as 101,325 pascal. [e]
- Bar (unit) [r]: A unit of pressure measurement (symbol: bar) defined as 100,000 Pascals. [e]
- International System of Units [r]: Metric unit system based on the metre, kilogram, second, ampere, kelvin, mole and candela. [e]
- Pascal (unit) [r]: The SI unit of pressure; the force of one newton acting uniformly over an area of one square metre. [e]
- Torr [r]: A non-SI unit of pressure (symbol: torr) with ratio of 760 to 1 atmosphere, selected to be approximately equal to the fluid pressure exerted by 1 millimeter of mercury (symbol: mmHg) and thus 1 torr ≈ 1 mmHg. [e]
- U.S. customary units [r]: The units of measurement that are currently used in the United States. [e]
- Boiling point [r]: The temperature at which the vapor pressure of the liquid equals the external environmental pressure surrounding the liquid and the liquid initiates boiling. [e]
- Fahrenheit (unit) [r]: A unit of temperature, defined by the melting point of water being at 32 degrees (°F), and the temperature difference between the melting and the boiling points to 180. [e]
- Rankine (unit) [r]: A unit of temperature, defined by absolute zero being at 0 degrees (°R), with 1°R being equal to 1°F (Fahrenheit), i.e. the temperature difference between the melting and the boiling points of water is set to 180. [e]
- Reference conditions of gas temperature and pressure [r]: The temperature and pressure conditions that define the density of a gas and serve to document a stated gas volume. [e]
- Reid vapor pressure [r]: A measure of the volatility of petroleum crude oil, gasoline and other volatile petroleum products that is widely used in the petroleum industry. [e]
- Temperature [r]: A fundamental quantity in physics - describes how warm or cold a system is. [e]
