What are the units to 0.0821?
The value 0.0821 refers to the ideal gas constant ( R ) in the context of the ideal gas law. Its units are typically expressed as liters times atmospheres per mole times kelvin (L·atm/(mol·K)). This constant is used to relate the pressure, volume, temperature, and amount of gas in various gas law equations.
What is universal molar gas constant?
The gas constant (also known as the molar, universal, or ideal gas constant, normally indicated by the symbol R) is a physical constant which is used in many of the fundamental equations in the physical sciences, such as the ideal gas law and the Nernst equation. It is equivalent to the Boltzmann constant, but expressed in units of energy (i.e. the pressure-volume product) per kelvin per mole (rather than energy per kelvin per particle). The gas constant uses the same units as specific entropy.Its value is: : R = 8.314472(15) J · K-1 · mol-1The two digits in parentheses are the uncertainty (standard deviation) in the last two digits of the value. The gas constant occurs in the simplest equation of state, the ideal gas law, as follows: : PV = nRT = nRT / V = RT / Vmwhere: : P: is the absolute pressure : T: is absolute temperature : V: is the volume the gas occupies : n: is the amount of gas (the number of gas molecules, usually in moles) : Vm: is the molar volume
Does the gas constant R vary with temperature?
No, the gas constant, or any constant, is constant meaning it doesn't change.
What is the constant equal to the ratio of the gas constant to the avogadro constant?
Boltzmanns constant
What is characteristic gas constant?
"Characteristic Gas Constant"The constant 'R' used in the characteristic gas equation PV=RT , has a constant value for a particular gas and is called 'Characteristic gas constant' or 'specific gas constant' . Its value depend upon the temperature scale used and the properties of the gas, under consideration.The value of R will be.For atmospheric pressure air,R= 287 J/kg/k
What is the R in the ideal gas law?

What are the units of the ideal gas constant with the value of 0.0821?
The ideal gas constant with a value of 0.0821 has units of liter·atm/(mol·K).
What is the constant for 1 mole of any ideal gas?
The Universal Gas Constant is 8.314 J/K/Mole
What are different NAME of constant r?
R may be the Rydberg constant or the gas constant.
What is the role of the ideal gas constant, denoted as R, in thermodynamics?
The ideal gas constant, denoted as R, is a constant used in thermodynamics to relate the properties of gases, such as pressure, volume, and temperature. It helps in calculating the behavior of ideal gases in various thermodynamic processes and equations, such as the ideal gas law.
What gas does the ratio of PV to RT equal a constant?
The ratio of PV to RT equals a constant for an ideal gas, as described by the ideal gas law: PV = nRT. Here, P represents pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is temperature in Kelvin. For a given amount of ideal gas at constant temperature and pressure, this ratio remains constant, illustrating the direct proportionality between the gas's volume and the product of its pressure and temperature.
What is the ideal gas constant of argon?
The ideal gas constant for argon is 0.2081 cal/(molK) or 8.314 J/(molK).
What is constant for 1 mole of any ideal gas?
The Universal Gas Constant is 8.314 J/K/Mole
What law relates pressure and temperature at a constant volume as temperature increases pressure increases?
The ideal gas law, also known as the equation of state for an ideal gas, relates the pressure, volume, and temperature of an ideal gas if the volume is kept constant. This law states that when the temperature of an ideal gas increases at constant volume, the pressure of the gas will also increase.
What is the relationship between the gas constant (R), temperature (T), and the number of moles (n) in the ideal gas law equation, 3/2nRT?
In the ideal gas law equation, the gas constant (R), temperature (T), and number of moles (n) are related by the equation 3/2nRT. This equation shows that the product of the number of moles, the gas constant, and the temperature is equal to 3/2 times the ideal gas constant.
What is ideal gas constant r?
It is the value of the constant which appears in an equation relating the volume, temperature and pressure of an ideal gas. Its value is 8.314 4621 Joules/(Mol K).
Relationship of temperature and pressure?
The ideal gas law states P*V=n*R*T where P is the pressure of the gas, V is the volume of the gas, n is the amount of substance of gas (also known as number of moles), T is the temperature of the gas and R is the ideal, or universal, gas constant, equal to the product of Boltzmann's constant and Avogadro's constant.
