Experimental Cognition
1. Capillary action refers to the phenomenon where liquid rises within a tube-shaped object due to the action of surface tension overcoming gravity. The hardboard used in sakura trees has many pores, allowing the liquid to climb up and spread quickly along the pores. It is similar to how a kitchen towel becomes wet when just one corner is wet, thanks to the powerful water-absorbing ability of capillary action.
2. Crystallization phenomena are everywhere in our daily lives, such as table salt, diamonds in nature (i.e., diamond), mica, and copper sulfate, etc., which are all crystal structures. The potassium dihydrogen phosphate used in the solution is also a crystal structure. In a certain temperature and a certain dose of solvent, when the amount of the solute reaches a certain degree, the solution will become saturated. If a certain amount of solvent is evaporated or the temperature of the solution is reduced, the solute may precipitate crystals from the solution, which is crystallization.
