Question

Why a thin layer is formed when hot tea is kept opened for some time?​

Answer 1

Answer:

When tea is heated rapidly, some of the water in it evaporates from the surface. This exposes proteins and fat molecules, which bind and dry out as warming continues. Skin most commonly forms when tea is heated over a stove top, as stoves are generally capable of reaching very high temperatures quite quickly, though it can happen in the microwave as well. The film is not harmful, but is distasteful to many and can be prevented with constant stirring and a close eye on temperature.
