Question

helium gas is present in a 100 l container at 27°C and collision frequency (Z11) is x unit at same temperature volume is reduced such that collision frequency becomes 4x unit what is the difference in volume of helium gas in initial state and final state in litres​

Answer 1

Answer:

so the final temperature is 927°C

Answer 2

Answer:

75 litres

Explanation:

Given:

Initial volume of helium gas present in a container is (V1) = 100 litres

Final volume of helium gas at the same temperature is (V2) = ?

Initial collision frequency (Z1) at volume V1 = x

Final collision frequency (Z2) at volume V2 = 4x

As we know that,

Collision frequency (Z) is inversely proportional to volume,

$z \alpha \frac{1}{v}$

$\frac{z1}{z2} = \frac{v2}{v1}$

so,

$\frac{x}{4x} = \frac{v2}{100}$

$\frac{1}{4} = \frac{v2}{100}$

$v2 = \frac{100}{4}$

Therefore,

V2 = 25 litres

Hence, difference in volume of helium gas is = Final - Initial

= 100- 25

=75 litres

RESULT: Difference im volume of helium gas is 75 litres.
