You have been swimming in your neighbor’s pool for an hour. The relative humidity of the air is 30 percent and has a normal temp
erature of 75°F. Will you feel warmer or cooler when you step out of the pool? Explain your answer using the given relative humidity of the air, and the process going on to make you feel warmer or cooler (the temperature outside will not affect you as much in this case).
One can feel warmer when you step out of the swimming pool because water conducts heat away from the body 20 to 27 times faster than air. So, when we enter into the water and are wearing little or no thermal protection, it actually increases r exposed body surface area and thus increases the rate at which your body heat is transferred to the water, that’s why one feels cold. One can maintain core temperature of the body during swimming only in water that's warmer than 75°F.
Well, nitrogen is the gas that makes up 78% of the earth's atmosphere.
I would guess its in the air that we breathe. I am not really sure. Just basing this answer off of research.
