# The constant R is called the ideal gas law constant. Its value depends on the units used to express pressure and volume. Table 6.1 “Values of the Ideal Gas Law

Del 1: Ideal Gas Law Den ideala gaslagen uttrycks med formeln: PV = nRT var. P = tryck. V = volym n = antal mol gas. R = ideal gasskonstant = 0,08206 L · atm

The ideal gas law describes the behavior of an ideal sample of gas, and how that behavior is related to the pressure (P), temperature (T), volume (V), and molarity (n) of the gas sample. In the equation PV=nRT, the term “R” stands for the universal gas constant. R is the gas constant in the ideal gas equation pV = nRT R is related to the Boltzmann constant, k, by R = k NA where k = 1.3806 x 10-23 J K-1, and N A = 6.022 x 10 23 mol-1 where n is the number of moles of the gas and R is the ideal gas constant. Ideal gases are defined as having molecules of negligible size with an average molar kinetic energy dependent only on temperature. At a low temperature, most gases behave enough like ideal gases that the ideal gas law can be applied to them. The ideal gas law in terms of R is PmRTV , where P is the absolute pressure of the gas, V is the volume occupied by the gas, m is the mass of the gas, and T is the absolute temperature of the gas.

Value Of Gas Constant The value of R at atm that is at standard atmospheric pressure is R = 8.3144598 J.mol-1.K-1. However, temperature must always be in Kelvin (K), as R uses units of K. There is a variation of the ideal gas law that uses the density of the gas with the equation P M = DRT where M is the molar mass in g/mol and D is the density of the gas in g/L. The ideal gas law describes the behavior of an ideal sample of gas, and how that behavior is related to the pressure (P), temperature (T), volume (V), and molarity (n) of the gas sample. In the equation PV=nRT, the term “R” stands for the universal gas constant.

The Maxwell-Boltzmann distribution. 2015-10-26 · For chemists, R = 0.0821 *L*atm*K^-1 *mol^-1, the value is usually most useful in that both litres and atmospheres are handy units (more so than m^3 and Pascals). When pressure is measured in Pascals, R = 8.314*m^3*Pa*K^-1mol^-1. Note here that volume is measured in m^3; 1 m^3 = 1000 L. 2018-10-03 · ideal gases and the ideal gas law This page looks at the assumptions which are made in the Kinetic Theory about ideal gases, and takes an introductory look at the Ideal Gas Law: pV = nRT.
