Q. A vessel containing $5\ litres$ of a gas at $0.8\ m$ pressure is connected to an evacuated vessel of volume $3\ litres$. The resultant pressure inside will be (assuming whole system to be isolated)
A) $4/3\ m$
B) $0.5\ m$
C) $2.0\ m$
D) $3/4\ m$
Explanation
(b) $0.8 \times 5 = P \times (3 + 5) \Rightarrow P = 0.5\ m$
