because we put air from our mouth and the tea gets cold
The heat is lost faster through metal than through glass or ceramic.
Hot vapors are rising from the tea. When you blow these vapors away more can rise faster to replace them. Thus more hot vapor (and thus more heat) can leave the tea while you are blowing than when you are not and the tea cools faster.
This is the process which some use in the preparation of Tea.
bubble tea is blowing up
tootsie rolls
Ice tea with lemon
sugar added to tea reduces the original specific heat capacity of water ,thus water is cooled faster.
Almost all chemicals are more soluble at high temperature than they are at lower temperature, so the tea infuses into the water more rapidly when the water is hot or boiling.
Yes, the food that is hot trades its heat inside with the cooler air around it blowing on it makes this process speed up.
White tea. Green tea. Oolong tea. Black tea. Rooibos tea. Mate tea. Herbal tea. and more.
You say "More tea please"
Temperature is the amount of random motion taking place on an atomic or molecular level. So, in hot water, the water molecules are moving around a lot more than those of cold water. These rapidly moving molecules have the capability of detaching other molecules from a solid to which they are attached, so that they become dissolved in the water. So the flavoring chemicals in tea leaves can be dissolved into the water more rapidly by hot water.
