Due to a connection error, a tank containing helium under pressure of 18,251 MPa was connected to an unplanned tank for high pressure (Pmax = 400 kPa) and containing nitrogen under 167.5 kPa absolute pressure. The interior volume of the Helium tank is 86.4 L and n is 6,0456 M3. The volume of the piping is negligible. Is the reservoir of nitrogen resist increasing pressure due to the arrival of the Helium if the temperature is 27 oC?
