Gas concentration vs temperature
« on: September 23, 2019, 03:48:47 PM »
If I inject 1 g of a gas in a closed volume, why should I expect different ppm(v) at different temperatures?
Shall it be the same ppm(v) regardless of the temperature since I am injecting the same amount of gas in the same closed volume? I think it will be different from the equation of state but I do not understand why. Please help. Any references?

Thank you

1g stays 1g no matter how much the temperature raises, and likewise the mole or mass fraction  But the concentration can change if the volume changes with T.
