pressure-temperature relationship
1Thermodynamic temperature — is the absolute measure of temperature and is one of the principal parameters of thermodynamics. Thermodynamic temperature is an “absolute” scale because it is the measure of the fundamental property underlying temperature: its null or zero point …
2International Temperature Scale of 1990 — The International Temperature Scale of 1990 (ITS 90) is an equipment calibration standard for making measurements on the Kelvin and Celsius temperature scales. ITS–90 is an approximation of the thermodynamic temperature scale that facilitates the …
3Temperature — This article is about the thermodynamic property. For other uses, see Temperature (disambiguation). A map of global long term monthly average surface air temperatures i …
4Pressure — This article is about pressure in the physical sciences. For other uses, see Pressure (disambiguation). Pressure as exerted by particle collisions inside a closed container …
5Pressure sensor — Digital air pressure sensor Compact digital barometric pressure sensor A pressure sensor measure …
6Pressure altitude — In aviation, pressure altitude is the indicated altitude when an altimeter is set to an agreed baseline pressure setting. This setting 101,325 Pa, equivalent to 1013.25 millibar (or hectopascals), or 29.92 inches Hg is equivalent to the air… …
7Blood pressure — For information about high blood pressure, see Hypertension. Blood pressure Diagnostics A sphygmomanometer, a device used for measuring arterial pressure. MeSH …
8Standard conditions for temperature and pressure — Not to be confused with Standard state. In chemistry, standard condition for temperature and pressure (informally abbreviated as STP) are standard sets of conditions for experimental measurements, to allow comparisons to be made between different …
9Wet-bulb temperature — The wet bulb temperature is a type of temperature measurement that reflects the physical properties of a system with a mixture of a gas and a vapor, usually air and water vapor. Wet bulb temperature can have several technical meanings:… …
10Critical temperature — The critical temperature, Tc, of a material is the temperature above which distinct liquid and gas phases do not exist. As the critical temperature is approached, the properties of the gas and liquid phases become the same resulting in only one… …
