What is the value of R?

The value of R at atm that is at standard atmospheric pressure is R = 8.3144598 J. mol-1. K-1.

What is r in PV nRT for mmHg?

The value of the gas constant ‘R’ depends on the units used for pressure, volume and temperature. R = 0.0821 liter·atm/mol·K. R = 8.3145 J/mol·K. R = 8.2057 m3·atm/mol·K. R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K.

What is P in PV NRT?

In the formula P V = N R T {displaystyle PV=NRT,} : P is the pressure of the gas. In SI units, this is measured in Pascals, or Newtons of force per square meter of area. (“Standard atmospheric pressure at sea level” is about 101,000 Pascals, or 101 KiloPascals.

What does N stand for in ideal gas law?

An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them may be deduced from kinetic theory and is called the. n = number of moles. R = universal gas constant = 8.3145 J/mol K. N = number of molecules.

What is r in pV nRT for Torr?

It is crucial to match your units of Pressure, Volume, number of mole, and Temperature with the units of R. … If you use the second value of R, which is 62.364 L Torr mol-1K-1, your unit for pressure must be Torr, for volume must be liter, and for temperature must be Kelvin.

What is Regnault?

Regnault’s Law states that the specific heat capacity of a gas at constant pressure (Cp) and the specific heat capacity of a gas at constant volume (Cv) do not change with change in pressure and temperature.
