TS EAMCET · Physics · Kinetic Theory of Gases
In a cubic container of inner side length \(10 \mathrm{~cm}\), nitrogen gas of \(100 \mathrm{kPa}\) pressure is maintained at \(300 \mathrm{~K}\). If the pressure inside the gas is increased to \(300 \mathrm{kPa}\) by adding oxygen gas, the ratio of number of \(\mathrm{N}_2\) to \(\mathrm{O}_2\) molecules in the container is
- A 0.5
- B 3
- C 1.5
- D 0.33
Answer & Solution
Correct Answer
(A) 0.5
Step-by-step Solution
Detailed explanation
As \(V\) and \(T\) are same for both gases, we can write \[ \left.\begin{array}{rl} p_1 V & =n_1 R T \\ p_2 V & =n_2 R T \end{array}\right\} \text { where } p_1 \text { and } p_2 \text { are partial } \] pressures of the gases.…
