good day!
i was asked to solve for gauge pressure, pg1, using the combined Boyle's and Charle's Law,
(pg1V1)T1=(pg2V2)T2
where V is the volume of gas and T is the temperature (in °C). now here's my question, we know that in computing for absolute pressure we need to convert the temperature to Kelvin (or Rankine) if the given is in °C, since gauge pressure is the difference between the absolute and atmospheric pressure, do i need to convert the given temperature in °K?
thanks and GB!
