Is the steam from a hot liquid the heating up of the liquid itself or the air around it?

Question

So if it’s the steam is a product of say the hot tea, would the liquid reduce as the steam is produced? Or is it the heating up of the air around it, so the amount of steam is only dependant on the temperature of the tea being more than the air around it?

Answer 1

The steam is the liquid itself. So yes, the liquid will reduce.

Actually, steam is just water. So not only will the level of the tea in the cup go down slightly, but the concentration of the tea will increase.
