Why does tea go cold?

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.
