The formula for absolute pressure is absolute P=gauge P+atmospheric pressure. So when the gauge is at 0 it's actually 1 atm. So using the gas law if I were to half the volume the pressure would increase to 2 atm. So would the gauge read 1 atm when this happens?
So how does the mechanism allow it to read the absolute pressure minus the atmospheric pressure only?
Thanks :)
