Vapour is injected at a uniform rate in a closed vessel which was initially evacuated. The pressure in the vessel
View answer and explanation
Correct option: C
First increases and then decreases
Option D (First increases and then becomes constant) is the correct answer. Initially, the pressure increases as vapor is injected. Once the saturation vapor pressure is reached, the vapor starts to condense, and the pressure remains constant.

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
