hmm

you're blowing away the moist air with condensation in, so dry air can make contact and pull away more water vapor thus cooling it down? Also the tiny little ripples you create increases the surface area...

depending on original temperature of tea

yes

the power of my degree tells me that blowing over it causes the bernoulli effect. this lowers the air pressure of the air being blown and makes it easier for the tea to evaporate and thus cool.

ehwhat is right though. not much.

yes

1) the cold air gets heated by the tea, making the tea less hot
2) the disturbance to the surface increases its surface area, meaning that it heats up more air
and it probably moves the tea around a bit, making the hot tea at the bottom come to te surface

yes

Though its best to blow on the tea just as you pour it into your mouth so that you are blowing on less tea by the time it hits your tongue and preventing it from burning you. This is how I drink really hot tea.

That 0.000223? reduction makes all the difference.

also holding the cup should cool it a bit quicker

than leaving it on the table, well if you hold the mug that is, rather than the handle.
