Definition: Absorbing is a verb which means to be attracted or influenced by something. In other words, it is the property of an object that causes it to become more permeable than before, i.e., its density increases. So for example, if you have a small bottle (a tube), and you put in some ink, then when you look at the ink, your eyes absorb it. When we talk about something being "absorbed" in water, it is referring to how much of the thing's substance or content has been absorbed into the liquid.
