Question

Why the gas constant 'R' is called Universal gas constant?

Answer 1

The gas constant is also known as the molar, universal, or ideal gas constant, denoted by the symbol R or R and is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure-volume product, rather than energy per temperature increment per particle.

Answer 2

Answer:

R is called universal gas constant

Explanation:

The value of R is 0.0821 dm3.It means that if we have one mole of an ideal gas at 273.16 K and one atmospheric pressure and it's temperature is increased by 1K then it will absorb 0.0821 dm3-atm of energy.Hence, value of constant R is a universal parameter for all gases.It tells us that the Avogadro's number of molecules of all the ideal gases have the same demand of energy.Hence R is called the universal gas constant.
