While sitting in an air conditioned rom your wet hair will make u cooler than your dry hair why?

the water acts as conductor for the heat which is passed frm the head to the atmosphere and the atm which is at a lower temp keeps taking this heat and circulates through the a.c

It is because water evaporating takes energy away which causes a noticeable drop in temperature.

Hair has a lot of surface area in relation to its volume. It therefore will hold a fiar amount of liquid. An air-conditioned room has a fairly low relative humidity and therefore can absorb a lot of water vapor. In order for the water in your hair to evaporate (ie go from a liquid state to a gaseous state) it needs energy since gas is more energetic than liquid. It gets this energy from the heat in your body. That's why your head will feel cool.

because dry hair is a good insulator of heat, while water conducts heat, and also evaporates, carrying heat away with it.
