A closed vessel contains pure water, in thermal equilibrium with its vapour at 25°C (Stage#1), as shown.The vessel in this stage is then kept inside an isothermal oven which is having an atmosphere of hot air maintained at 80^{∘} {C}. The vessel exchanges heat with the oven atmosphere and attains a new thermal equilibrium (Stage #2). If the Valve A is now opened inside the oven, what will happen immediately after opening the valve?
