Eli5: Why dose warm/hot water come out of the tap “milky” or foggy white when cold water comes out clear?
In: Chemistry
Fun trick, if it comes out really milky and clears after a few minutes (this means there is undissolved air in the form of countless miniature bubbles (the smaller the bubble the longer it will take to clear) then pour some into a ceramic mug, put a spoon in the mug and tap the bottom of the mug repeatedly with the spoon. You should get an awesome hollow sound. I believe the technical term fruit this is actually “the hot chocolate effect” as this is the best example. The sound will change slowly as the bubbles come out.
