The volume of a gas at \(30^{\circ} \mathrm{C}\) temperature and \(760 \mathrm{~mm}\) of \(\mathrm{Hg}\) pressure is \(100 \mathrm{cc}\). Then its volume at the same temperature and \(400 \mathrm{~mm}\) of \(\mathrm{Hg}\) is
- A \(190 \mathrm{cc}\)
- B \(210 \mathrm{cc}\)
- C \(150 \mathrm{cc}\)
- D 120 cc
Answer & Solution
Correct Answer
(A) \(190 \mathrm{cc}\)
Step-by-step Solution
Detailed explanation
Given, initial volume \(=100 \mathrm{~cm}^3\) Initial pressure \(=760 \mathrm{~mm}\) of \(\mathrm{Hg}\) Initial temperature \(=30^{\circ} \mathrm{C}\) And, final temperature \(=\) Initial temperature So, change is isothermal. Also final pressure \(=400 \mathrm{~mm}\) of…
