Using Henry’s law, show that the dissolved gases in a liquid can be driven off by heating the liquid.
What will be an ideal response?
Henry’s law is expressed as
Henry’s constant H increases with temperature, and thus the fraction of gas i in the liquid yi, liquid side decreases. Therefore, heating a liquid will drive off the dissolved gases in a liquid.
