Q: This inverse relationship between solubility and temperature can be understood by looking at a what?


Read this paragraph and choose the correct option from the provided answers:

This inverse relationship between solubility and temperature can be understood by looking at a molecular model. Recall that higher temperatures are associated with faster particles. Gas particles are held in solution by attractive interactions with the solvent molecules. If the particles are moving slowly, these attractive forces will pull back any particles that try to escape the surface of the solution and re-enter the gas phase. However, if the gas particles are moving fast enough, these interactions will not be sufficiently strong to prevent this process from occurring. As a result, more particles are able to escape, and the amount of dissolved solute is less than it would be at a lower temperature.

 Choices:

- nutrient model

- a slide

- potassium model

- molecular model


A:
molecular model
