ideal gas law Also found in:Encyclopedia,Wikipedia. n. A physical law describing the relationship of the measurable properties of an ideal gas, where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin). It is derived from a combinati...
The Ideal Gas Law can be expressed with the Individual Gas Constant . p V = m R T (4) where p = absolute pressure [N/m2], [lb/ft2] V = volume [m3 ], [ft3 ] m = mass [kg], [ slugs ] R = individual gas constant [J/kg K], [ft lb/slugs o R] T = absolute ...
Equation 1.19: Ideal gas law using mass of gas and molar weight (1.19)PV=mMRT Example 1.8 One pound-mole of an ideal gas occupies 378.6 standard ft3. Calculate the value of the universal gas constant, parameter R. Answer The parameter n is equal to 1 pound-mole. According to Amagat’s...
This chapter presents ideal gas laws. The relationship that exists between pressure, volume, and temperature of a gas are given in a set of laws called the gas laws. Changes that occur at constant temperature are called isothermal changes. According to Charles' law, for a given mass of gas...
