The variation of solubility for a gas with temperature can be determined by examining the graphic on the left.
As the temperature increases, the solubility of a gas decrease as shown by the downward trend in the graph .
More gas is present in a solution with a lower temperature compared to a solution with a higher temperature.
The reason for this gas solubility relationship with temperature is very similar to the reason that vapor pressure increases with temperature. Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in molecules which break intermolecular bonds and escape from solution.
