Question

[Single-digit Integer] Two identical vessels are connected by a tube with a valve letting the gas pass from one vessel into the other if the pressure difference, ΔP ≥ 2.0 atm. Initially there was a vacuum in one vessel while the other contained ideal gas at a temperature 300 K and pressure 4.0 atm. Then both vessels were heated to a temperature 600 K. Up to what value will be the pressure (in atm) in the first vessel (which had a vacuum initially) increase?

Prashant Kotian · Accepted Answer

Correct answer: 0001. Initially Vessel 1 at 4 atm, Vessel 2 vacuum ( atm). Valve opens. Gas flows until pressures equalise: atm. Now atm, valve closes. At constant temperature pressures don't change further. Valve opened exactly time.
