Question & Answer: Explain why oxygen is more soluble in cold water than in warm water. Use both the…..

As temperature increases, kinetic energy increases. The greater kinetic energy results in greater molecular motion of the gas particles. As a result, the gas particles dissolved in the liquid are more likely to escape to the gas phase and the existing gas particles are less likely to be dissolved. The converse is true as well.
The trend is thus as follows: increased temperatures mean lesser solubility and decreased temperaturesmean higher solubility.
