What does the Constant R in the Ideal Gas Law mean?
2 Answers
Regnault constant, or Universal Gas Constant.
Explanation:
Gas constant, R, is named after the French chemist Henri Victor Regnault. It is also called the Universal Gas Constant.
Gas constant is equivalent to Boltzmann constant
There are many values of R depending on the units used.
Here are some examples:
R can be viewed as a scaling factor for molar energy of ideal gas law. For ideal gas law, energy can be viewed as increasing linearly with temperature.
Explanation:
Through derivation. it was shown that for one-dimension,
The above is for 1 mole of ideal gas. For 1 molecule of gas, we know that
So 1 molecule of ideal gas moving in 3 dimension is
You can equate the kinetic energy of the molecule
