Paper absorbs water because of its porous nature. The fibers in paper create small spaces and channels that allow water to be drawn in through capillary action. When water comes into contact with paper, it is able to penetrate the spaces between the fibers, causing the paper to become saturated. This absorption is what allows paper to become damp or even completely wet when exposed to water. **
