effect of temperature on gas pressure
Posted: Fri Aug 03, 2012 7:29 am
Hi again,
My second problem is this:
I have a sealed cylinder which I will heat up. I assume the cylinder is not expanding significantly with heat and not deforming with internal pressurization.
In the first case I will fill it with water prior to heating. As it is gas-tight, I would like to know what the calculated pressure increase will be. I would like to arrive at a curve from which I can point to the phase change to vapour and from which I can estimate the internal pressure at a given temperature above the boiling point.
In the second case I will fill it half full with water prior to heating. What will the result be then and how can I use the knowledge of the fraction of water in the vessel to estimate the differences in pressure accordingly??
As always, I am excited for your help!
Best regards and thanks.
