A rigid insulated tank is initially evacuated. It is connected through a valve to a supply line that carries air at a constant pressure and temperature of 250 kPa and 400 K respectively. Now the valve is opened and air is allowed to flow into the tank until the pressure inside the tank reaches to 250 kPa at which point the valve is closed. Assume that the air behaves as a perfect gas with constant properties

A rigid insulated tank is initially evacuated. It is connected through a valve to
a supply line that carries air at a constant pressure and temperature of 250
kPa and 400 K respectively. Now the valve is opened and air is allowed to flow
into the tank until the pressure inside the tank reaches to 250 kPa at which
point the valve is closed. Assume that the air behaves as a perfect gas with
constant properties
(𝒄 𝒑 = 1.005 kJ/kg.K, 𝒄 𝒗 = 0.718 kJ/kg.K, 𝑹 = 0.287 kJ/kg.K). Final
temperature of the air inside the tank is ___________ K (round off to one
decimal place).
