A first answer would be that when you touch water wet because we feel our fingers tell the brain that the sensation caused by touching the water is "wet".
Nerve impulses send messages all the time from skin to brain communicate things about the world around us. This phenomenon is called the sense of touch and he tells us when things are touch dry, hot or cold, soft or hard. We feel that water is wet because it is a liquid. However, it is liquid only when its temperature is between 0 and 100 degrees Celsius. At zero degrees, or less, the water turns to ice, and at over 100 degrees water enters gaseous, turning into water vapor.
