Hey everyone, we're asked to identify the following statement as correct or incorrect. The scalability of gasses and water is inversely proportional to the temperature because the solute solvent interactions are weakened at high temperatures. Now, we've learned at high temperatures our kinetic energy of our molecules will increase and this is because they are able to overcome the attractive forces among them at low temperatures. Our molecules do not have enough energy to overcome those inner molecular attractive forces. Because of this reason, the soluble itty of gasses in water increases at low temperature. And this is because the molecules do not have enough energy to overcome attractive forces and escape the solution. So, as we can see right here, temperature and scalability of gasses are inversely proportional. So our statement here is going to be correct now, I hope that made sense. And let us know if you have any questions.
