If a pressure gauge on a tank reads 2.5 bar and the local atmospheric pressure is 1.0 bar, what is the absolute pressure inside the tank?

Correct answer: 3.5 bar

Explanation

This question tests the practical calculation of converting a gage pressure reading to an absolute pressure, which is necessary for most thermodynamic formulas. Absolute Pressure = Gage Pressure + Atmospheric Pressure.
