(II)

r.m.s.

speeds of different gases are same at same temperature
(III) For one gram of all ideal gas kinetic energy is same at same temperature
(IV) For one mole of all ideal gases mean kinetic energy is same at same temperature

View answer and explanation

Correct option: D

None of these

Option D (None of these) is correct because all the given statements are incorrect based on the kinetic theory of gases.

The absolute zero is the temperature at which The internal energy

\left( U \right)

\left( p \right)

\left( V \right)

of an ideal gas are related as

U = 3pV + 4

. The gas is A monoatomic ideal gas is contained in a rigid container of volume

V

with walls of total inner surface area

A

x

and thermal conductivity

K

. The gas is at an initial temperature

T_0

P_0

. If the pressure of the gas as a function of time if the temperature of the surrounding air is

T_{\mathrm{s}}

\frac{T_0}{T_0}\left[T_s-\left(\mathrm{T}_s-T_0\right)_e \frac{-Z k A}{3 x R} t\right]

. Find the value of

z

. All temperatures are in absolute scale. Assertion: The change in air pressure effect the speed of sound.
Reason: The speed of sound in a gas is proportional to the square of pressure. The rms speed of oxygen molecule in a vessel at particular temperature is

\left(1+\frac{\gamma}{28}\right)^{\frac{1}{2}} v,

v

is the average speed of the molecule. The value of

\gamma

\left(\pi=\frac{22}{7}\right)

For an ideal gas the instantaneous change in pressure

p

V

is given by the equation

\frac{{dp}}{{dV}}\, = \, - ap.

p\, = \,{p_0}

V\, = \,0

is the given boundary condition, then the maximum temperature one mole of gas can attain is (Here

R

is the gas constant)
