how the solubility of a gas on water changes qwith increase in its temperature |
| Answer» <p>For Gases, solubility decreases as temperature increases. The physical reason for this is that when most gases dissolve in solution, the process is exothermic. This means that heat is released as the gas dissolves. This 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 the gas molecules which break intermolecular bonds and escape from solution.</p> | |
