If I fill a water bottle with room temperature water. And I put it in the shower. And I take a hot steamy shower. Why does the water in that bottle feel cold when I pour it?
In: Chemistry
Water is really, really good at moving heat. It’s also really, really heavy and takes a lot of energy to warm it up.
In a hot steamy shower the room temperature water bottle (about 70 degrees) will absorb some of the heat from the hot shower water (around 100-130 degrees). The surface of your skin will warm up much faster as you bathe.
When you pour water out of the bottle over your hands, your warm skin will be cooled rapidly by the now 75-80 degree water, making it feel cold, even though it’s objectively quite warm.
