The boiling water for tea primarily involves convection as the heat is transferred through the movement of water molecules. As the water at the bottom of the pot is heated, it becomes less dense and rises, while cooler, denser water descends to take its place, creating a circulation pattern. Additionally, conduction occurs between the hot pot and the water, transferring heat directly to the water molecules in contact with the pot's surface.
There are more molecules to heat up in a pot of tea than in a small cup. The molecules have more space to move around, thus creating more energy.
Both the evaporation of sweat from the body and the boiling of water in a tea kettle involve the transition of a liquid to a gas, which requires energy. When sweat evaporates from the skin, it absorbs heat from the body, helping to cool it down, similar to how the water in a kettle absorbs heat from the stove until it reaches its boiling point. In both cases, the process of evaporation removes heat from the surrounding environment, whether it's the body or the kettle, resulting in a cooling effect.
When a tea bag is placed in water, the water fills the tea bag. The soluble matter of the tea leaves, what essentially makes the tea, then diffuses into the water through the bag. The brown coloring is a result of this process.
Any liquid that's added with heat can boil. Example: bubbling water or bubbling gravy. e.g water to bubbling water
The commercial process for removing caffeine from tea is fairly complex, however, according to my Chinese medicine doctor, if you pour boiling water over your tea (leaves or bagged) leave it for 20 - 30 seconds, pour out the "first" steep and re-fill your cup/pot with more boiling water. The resultant tea will be greatly reduced in its caffeine content.
I think the transfer of heat depending on if you have a tea bag is actually from the tea bag.....

Boiling tea kettle loses water through vapourization mainly not by evoporation.

The energy output of a whistling tea kettle is in the form of sound and heat. As the water boils and creates steam, the kettle whistles to signal that the water is ready. The heat energy is transferred to the water to raise its temperature to boiling point.
Heat the water in the tea-pot n when the water starts boiling put the Darjelling tea leaves in it n cover it n keep aside.Take sugar(according how sweet u want) in a cup n strain the tea water in the cup.Stirr it n enjoy the green tea of Darjeeling
starting from absolute zero, even twice as much water as the tea would contain more heat. Even starting at 0 Celsius underwater volcanoes would heat water far beyond boiling. On a percentage of heat the tea would win.
Tea leaves go in boiling water to turn black.
Using a copper tea pot for brewing tea can provide benefits such as even heat distribution, quick boiling time, and potential health benefits from copper ions in the water.
Tea is made with fresh boiling water, hence hot.
It is not the teabag that colours the water but the tea leaves which are inside the bag, They contain various chemicals and some of these dissolve in water giving it the characteristic flavour and colour of tea.
