The gas constant (R) is a physical constant that relates energy, temperature and amount of substance in the ideal gas law and other equations. Learn how it is defined, what its value is in different units, and how it relates to the Boltzmann constant and the Avogadro constant.
11 lut 2021 · R is the gas constant used in the ideal gas law and Nernst equation. Learn its value in different units, its relation to the Boltzmann constant, and its symbol history.
30 sty 2023 · Learn the definition, equation and applications of the ideal gas law, which relates pressure, volume, temperature and number of moles of a gas. Find out how to derive and use the simple gas laws (Boyle's, Charles', Avogadro's and Amonton's) and the standard temperature and pressure (STP).
The ideal gas law is an equation of state that describes the behavior of a hypothetical ideal gas. It relates the pressure, volume, temperature and amount of substance of a gas, and can be derived from kinetic theory or empirical laws.
The ideal gas law is the equation of state for an ideal gas, given by: = where P is the pressure; V is the volume; n is the amount of substance of the gas (in moles) T is the absolute temperature; R is the gas constant, which must be expressed in units consistent with those chosen for pressure, volume and temperature.
30 sty 2023 · Explain all the quantities involved in the ideal gas law. Evaluate the gas constant \(R\) from experimental results. Calculate \(T\), \(V\), \(P\), or \(n\) of the ideal gas law: \(P V = n R T\). Describe the ideal gas law using graphics.
The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.
