SUMMARY
The discussion clarifies the distinction between agitation and heat at the atomic scale, particularly in the context of dissolving salt in water. Increasing the temperature of the water enhances the dissolution rate due to increased molecular movement, while agitation, such as stirring, facilitates diffusion by moving low concentration regions closer to the solute. The conversation references Joule's experiment, which demonstrated that mechanical work can convert to heat, establishing the Mechanical Equivalent of Heat, where 4.2 Joules of work produces one calorie of heat. This highlights the efficiency difference between agitation and thermal energy in influencing molecular interactions.
