Statement-I: Boltzmann's constant is a gas constant for 1 molecule of a gas
Statement-II: Universal gas constant is a gas constant for 1 mole of a gas
Statement-II: Universal gas constant is a gas constant for 1 mole of a gas
View answer and explanation
Correct option: A
Statement-I and statement-II are true
Option A (Statement-I and statement-II are true) is correct because Boltzmann's constant is the gas constant for one molecule, and the universal gas constant is for one mole.

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If is the velocity of sound in air and is the rms velocity, then Four particles have velocities . The root mean square of the particles is (in ) The translational degrees of freedom and rotational degrees of freedom of molecule are: On any planet, the presence of atmosphere implies (= root mean square velocity of molecules and escape velocity) At a given temperature, the pressure of an ideal gas of density is proportional to
