Why does tea go cold?

Answer 1

Tea gos cold in many ways one way is conduction this causes heat to be passed and spread along the cup this takes heat with it at the same time, another way is convection this is because hotter air is less dense so is at the top of the cup but is cold at the bottom of the cup, one other way is radiation this radiates heat taking heat with it, the final one is evaporation because the liquid has turned into a gas and then it rises due to the fact it has less density so rises it then takes heat with it.

Answer 2

Well a teapot is a closed area and doesn't let much air go out so the steam just sits there and keeps the tea hot. In a teacup there is a wide surface area where's there's a lid or top so the steam just rises up, out of the cup letting it get colder and colder.

Answer 3

Hot tea releases steam, and if the cup is colder than the steam, condensation may form. Although in most cases the cup will rapidly warm up to the same temperature as the hot tea that it contains, and will then not form condensation.

Answer 4

A good cup of tea is made with boiling water (212 F). If you don't let it cool it will burn your mouth.

Answer 5

Unless you used instant tea you need hot water to brew the tea bag or leaves.
