Question 3 :
<p>How many times is the weight of the air filling a room in winter ($7^{0}C$) greater than weight in summer $(37^{0}C)$ ? Assume that pressure is constant.</p>
Question 4 :
The relation PV=RT can describe the behavior of a real gas at :
Question 7 :
According to the Boltzmann's law of equipartition of energy, the energy per degree of freedom and at a temperature T K is :
Question 8 :
<p class="wysiwyg-text-align-left">The temperature at which the volume of ideal gas is zero is:</p>
Question 10 :
At room temperature (27$^0$ C) the rms speed of the moleculesof certain diatomic gas is found to be 1920 ms$^{-1}$ then the molecule is:
Question 11 :
Assertion: Rate of diffusion of a gas is inversely proportional to the square rate of its density
Reason: Hydrogen is the lightest gas known. so it diffuses most readily
Question 13 :
In Rutherford's experiment, most of the alpha particles are observed to

Question 16 :
Assertion: Vibrational energy of diatomic molecule corresponding to each degree of freedom is ${ k }_{ B }T$.
Reason: For every molecule, vibrational degree of freedom is 2.
