One of my university doctors asked a question and I couldn't find an answer for so If anyone can help I will appreciate that. The question is why in thermodynamics we usually work with absolute pressure instead of gage pressure where in fluidmechanics we use gage pressure.

✨✨✨the vacuum of space, there iseffectively no pressure, but at sea level the pressure is, on average, 14.696 psia (absolute). Thus, cities at sea level have higher atmospheric pressures than cities in the mountains. ... Gaugepressure of a process increases as atmospheric pressure decreases.✨✨✨
