Q. The gas constant R is derived from __________.

गैस स्थिरांक R __________ से प्राप्त होता है।

Avogadro’s number
अवोगाद्रो की संख्या

Planck’s constant
प्लैंक स्थिरांक

Boltzmann constant
बोल्ट्ज़मान स्थिरांक

Newton’s constant
न्यूटन स्थिरांक

The universal gas constant $R$ is related to the Boltzmann constant $k$ by:

R = k \cdot N_A

Where:

$k$ = Boltzmann constant
$N_A$ = Avogadro’s number
So, R is derived from the Boltzmann constant and molecular theory of gases.
