From the tutorial, the air (Material: Air at 25 C) is initially at 5ºC and one side is heated up with fixed temperature of 75ºC and the opposite side is maintained at 5ºC. From the result, why the pressure changes not so much? In my opinion refers to ideal gas law, the pressure should increase about 0.25atm. If I want to see 0.25atm increasing, how can I do? And also, what is the different between "Total Pressure" and "Pressure"? Thank you so much. Noppawit
