Two thermally insulated vessels are connected by a narrow tube fitted with a valve that is initially closed as shown in the figure below. One vessel of volume V1 = 15.1 L,contains oxygen at a temperature of T1 = 320 K and a pressure of P1 = 1.70 atm. The other vessel of volume V2 = 22.5 L contains oxygen at a temperature of T2 = 445 K and a pressure of P2 = 1.90 atm. When the valve is opened, the gases in the two vessels mix and the temperature and pressure become uniform throughout.

Can someone pls explain to me how you would go about solving this question, I have looked through my physics text book but finding it hard to know where to start with this question.
