Kinetic Theroy of gases

What is the average velocity of gas molecules of an ideal gas?

• 0

• ∞

• $\sqrt{\frac{8KT}{m\pi}}$

• Can't say anything

Pressure exerted by a gas depends on:

• Volume of gas chamber

• Density of gas

• Density of glass of chamber

• speed of gas molecules

Degree of freedom of a diatomic gas molecule is:

• 6

• 5

• 7

• undefined

According to Law of Equipartition of Energy

• Energy of the system of particles is equally distributed amongst various degrees of freedom

• energy possessed by each particle in each degree of freedom is KT/2

• All the above

Unit of Specific heat in SI unit is:

• J/kg/K

• erg/gm/K

• erg/Kg/K

• All the Above

According to Maxwell speed distribution Law , Most probable speed relationship with Temperature is:

• it does not depend on temperature

• increases with increase in temperature

• decreases with increase of temperature

• don't know the answer

According to Distribution Law, r.m.s speed is

• $\sqrt{\frac{3kT}{m}}$

• $\sqrt{\frac{3kT}{m\pi}}$

• $\sqrt{\frac{8KT}{m\pi}}$

• $\sqrt{\frac{2kT}{m}}$

According to Maxwell's Energy Distribution Law, distribution of molecules P(E) is independent of

• Energy (E)

• mass of a molecule (m)

• Temperature (T) of the gas

• none of the above is correct

y in the graph, According to Maxwell Distribution Law, represents:

• Fraction of total molecules having speed between c and c+dc, dn/n

• no of molecules, n

• speed (c)

• All of the above

The above equation is giving us:

• no of molecules having speed between c and c + dc

• no of molecules having speed c

• no of molecules having speed dc

• I don't know the answer
