Homework Statement
What does the R in the ideal gas constant do.
I know its a proportionality constant and it comes from a variety of equations and is related to Boltzmann, but what does it do physically?
Gets you the right answer?monster101 said:but what does it do physically?
The Universal Gas constant R, also known as the ideal gas constant, is a physical constant that appears in the equation of state for ideal gases. It is represented by the symbol R and has a value of 8.314462618... J/(mol·K) in SI units.
The Universal Gas constant R is used to relate the physical properties of an ideal gas, such as pressure, volume, and temperature, to the amount of gas present. It is also used in various equations in thermodynamics and is a fundamental constant in the ideal gas law.
The Universal Gas constant R is calculated using the Avogadro constant, the Boltzmann constant, and the number of moles of gas. It is derived from the ideal gas equation PV = nRT, where P is pressure, V is volume, n is the number of moles, and T is temperature.
The units of the Universal Gas constant R are joules per mole per Kelvin (J/mol·K) in the International System of Units (SI). However, it can also be expressed in other units, such as liters·atmospheres per mole per Kelvin (L·atm/mol·K) in the imperial system.
The Universal Gas constant R is a universal constant and is the same for all ideal gases, regardless of their molecular weight or chemical properties. Other gas constants, such as the specific gas constant and the molar gas constant, are specific to certain gases and can vary based on their properties.
