Question

what happen when we put our hand in cold water​

Answer 1

Answer:

When you put your hands in the water, your brain gets information from your temperature receptors that say, "hey, that's hot" or "whoa, that's cold." If you keep your hands in the hot water or cold water long enough, your nerve receptors get used to the temperature of the water.
