Question

A vessel containing \(10\) liters of an ideal gas at a pressure of \(760\text{ mm of Hg}\) is connected to an evacuated \(9\) liter vessel. The resultant pressure is

• A. \(400\text{ mm of Hg}\)
• B. \(1440\text{ mm of Hg}\)
• C. \(40\text{ mm of Hg}\)
• D. \(760\text{ mm of Hg}\)

Hint:

When gas expands into an evacuated vessel at constant temperature, use Boyle's law \(P_1V_1=P_2V_2\).

Answer 1

The Correct Option is A
