the initial mass (m1) in (kg) :is A rigid 0.15 m³ tank contains air at 0.8 MPa, 200°C. A valve on the tank is now opened and air flows out until the pressure drops to 100 kPa. During this process, heat is transferred between tank and surrounding, such that when the valve is closed, the temperature inside the tank is 60°C. me Valve Tank Air, V-0.15 m² P₁=0.8 MPa, Ti= 200 C P₂-100 kPa, T₂ = 60°C Below 0.2 O Between 0.2 and 0.4 O Between 0.4 and 0.6 O Between 0.6 and 0.8 Above 0.8
