AP EAMCET · PHYSICS · Kinetic Theory of Gases
Pressure of a gas of constant volume at \(20^{\circ} \mathrm{C}\) is \(90 \mathrm{~cm}\) of \(\mathrm{Hg}\). At what temperature the pressure would change to \(75 \mathrm{~cm}\) of \(\mathrm{Hg}\) ?
- A \(233.2^{\circ} \mathrm{C}\)
- B \(-28.8^{\circ} \mathrm{C}\)
- C \(-24.2^{\circ} \mathrm{C}\)
- D \(28.8^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(B) \(-28.8^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
Given, \[ \begin{aligned} & T_1=(273+20) \mathrm{K}=293 \mathrm{~K} \\ & p_1=90 \mathrm{~cm} \text { of } \mathrm{Hg} \\ & p_2=75 \mathrm{~cm} \text { of } \mathrm{Hg} \end{aligned} \] Since, volume of the gas is constant. Hence, according to ideal gas equation,…
