How heat affects capillary action

“How does the temperature of a liquid affect it’s capillary action?”

 

Heat has an effect on a myriad of different properties of materials, but could it possibly have an effect on capillary action? Well, let’s use some of our scientific thinking to find out. We know that increasing the temperature of an object will weaken the intermolecular force of it, and we also know that the strength of capillary action is based upon the relative strength between the adhesive and cohesive forces of a liquid (Which we can symbolically summarize as cohesive force = adhesive – cohesive). So wouldn’t it be logical that if we could weaken the internal cohesive forces of a liquid through heating, that the adhesive forces would have more pull? According to scientific research, this hypothesis proves to be empirically valid!
