state of matter
distinct forms that different phases of matter take on
jet engine
reaction engine which generates thrust by jet propulsion
standard temperature and pressure
reference values for temperature and pressure
phase
region in a substance throughout which all physical properties are essentially uniform; region of material that is chemically uniform, physically distinct, (often) mechanically separable
vapor pressure
pressure exterted by a vapor in thermodynamic equilibrium
Dalton's law
physical law that the pressure of a mixture of ideal gases is equal to the sum of the partial pressures of its constituents
partial pressure
hypothetical pressure of gas if it alone occupied the volume of the mixture at the same temperature
equation of state
equation describing the state of matter under a given set of physical conditions
Raoult's law
law of thermodynamics
van der Waals equation
equation of state that generalizes the ideal gas law
Henry's law
a gas law that states that the amount of dissolved gas is proportional to its partial pressure in the gas phase
heat of combustion
quantity measuring the energy per unit of mass or volume that some substance releases upon oxidation
Joule–Thomson effect
temperature change of a real gas when undergoing a throttled expansion without heat transfer
volatility
tendency of a substance to vaporize
Clausius–Clapeyron relation
relation between vapour pressure and temperature
thermal efficiency
performance measure of a device that uses thermal energy, expressed as the ratio of work done over thermal energy used
liquid air
air that has been condensed into a liquid
Theorem of corresponding states
assertion that all fluids, when compared at the same reduced temperature and reduced pressure, have approximately the same compressibility factor and all deviate from ideal gas behavior to about the same degree
Redlich–Kwong equation of state
empirical algebraic equation of state more precise than the Van der Waals equation
air preheater
device to heat air in preparation for a following process
recuperator
thumb|400px|Types of recuperator, or cross plate heat exchanger A recuperator is a counter-flow energy recovery heat exchanger that recovers waste heat in the supply and exhaust air streams of an air-handling system or in the exhaust gases of an industrial process. Generally, they extract heat from the exhaust and use it to preheat air entering the combustion system, reducing the need for fuel and boosting the system's energy efficiency.
expander cycle
method of rocket engine operation
relative volatility
measure of vapor pressures of the components in a liquid mixture
Non-random two-liquid model
Model in physical chemistry
Inversion temperature
concept in thermodynamics
Dühring's rule
linear relationship between the temperatures at which two solutions exert the same vapour pressure
