Why does absorbed water leave the substance that absorbed it when you give that substance a good squeeze?
For that matter, how does absorbency work at all? Why can a sponge or towel absorb more water than say, a silver ingot? What allows anything to absorb anything else? Is there a scale that measures absorbency?
Harkening back to my first question, will absorbed radiation (or light or heat or whatever) also leave the substance that absorbed it if you give it a good squeeze? Are the laws of absorbency constant from one medium to another?
So many questions…
