The diameter of oxygen atom is

3\mathop A\limits^ \circ

. The fraction of molecular volume to the actual volume occupied by oxygen at STP is

View answer and explanation

Correct option: B

8 \times {10^{ - 4}}

Option B (

8 \times {10^{ - 4}}

) is correct because it represents the ratio of the volume occupied by oxygen molecules to the total volume at STP, considering the diameter of the oxygen atom.

The absolute zero is the temperature at which The internal energy

\left( U \right)

, pressure

\left( p \right)

and volume

\left( V \right)

of an ideal gas are related as

\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,

where

v

is the average speed of the molecule. The value of

\gamma

will be:

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

For an ideal gas the instantaneous change in pressure

p

with volume

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)
