Thank you all for replying. I think i will consider Andrew Mason's advice of looking for the change in internal energy. The process of removing air is by simple vacuuming and then isolating the control space. Zentrails, i know air is not ideal. But how else should i calculate for gases such...

Dear all, I would like to ask: Given a control volume (V1), at an initial temperature (T1), the pressure (P1) in the volume (V1) is decreased by sucking out air. The suction hole is then closed to achieve a state of P2 * V2 = n2 * R * T2 . What would happen to the temperature in the control...
