gâz-e ârmâni, ~-e minevâr
Fr.: gaz idéal
Theoretical gas assumed to consist of perfectly elastic molecules of negligible volume and mutual attraction force. Also called → perfect gas.
ideal gas law
qânun-e gâz-e ârmâni, ~ ~ minevâr
Fr.: loi des gaz parfaits
An → equation of state that relates pressure (P), temperature (T), and volume (V) of an ideal or → perfect gas: PV = nRT, where n is the number of → moles of gas present and R is the → universal gas constant. Equivalently: PV = NkT, where N is the number of atoms of gas present and k is → Boltzmann's constant.
