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.
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
sugar added to tea reduces the original specific heat capacity of water ,thus water is cooled faster.
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.....

the tea pot
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.
Boiling tea kettle loses water through vapourization mainly not by evoporation.
Boiling water on an electric stove,Putting a spoon in a cup of hot teaIce in tea
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
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.
yes
Actually you don't use "boiling" water, You are supposed to use water that has just quit boiling. The idea is that boiling will damage the leaves (tea is tea leaves) But the water should be just that hot to release the flavour properly and the tea should be allowed to steep for a few minutes and allow the leaves to release all their different flavours naturally with out stirring our damaging the leaves. If it is done properly you get a very nice effect that I am unable to taste, so I use boiling water and stir my tea as I am impatient and can't tell the difference.
You can brew Lipton green tea the same way you can brew any type of green tea. Heat the water (by any means, a kettle on the stove is the most common way), and then pour the water over the tea bag. Most people like the flavor of green tea best when it is not brewed with boiling water, but rather, water that has cooled slightly from boiling. Then you can steep for a few minutes (3 is a good starting point) and drink it. Some people like to add sugar or milk, but this is less common for green tea than it is for black tea.
