I'm guessing it's because the heat makes the moisture in the bread come to the surface, but why does it do that? And where is that moisture hiding before you toast the bread? The bread doesn't feel moist before you toast it, so where did the moisture come from? Is there some chemical reaction when you heat it that creates H2O? I'm just curious.

The moisture isn't "hiding". It's in the air, and in the bread you say doesn't feel moist before you toast it. If it didn't have any humidity in it, it would be ashes. So the moisture is all around you and your bread before you toast it. And once you realize that, you've already answered your question in the first part of your sentence in your detailing of your question. If heat rises, and you know it does, and if there's moisture all around, and you know there is, then the "sweating" that the substances will do under increased heat shows up as water, which is heavier than air, and therefore, it's on your napkin after you toast your bread and put it down on the napkin. You see, you already knew the answer. You just couldn't find the moisture that was sitting all around you. You're doing great. God Bless you.

Well, yes. It does contain moisture. Almost everything you eat does. When you put the bread in the toaster, it's flimsy, and when it comes out it's, well, toasted. It's stiff and hard (not to mention delicious!). There was a chemical reaction involved, and usually that kind of organic reaction will produce some water. But the water in the bread is brought out (notice how your bread is usually steaming when it comes out of the toaster?).

Warm air, which contains water vapour is held next to the napkin by the toast. As that air cools it releases the moisture. onto the napkin.
The same thing happens if you set a warm plate down on a counter top and leave it to cool.

Why don't you think the bread is moist --or contains moisture? That's wierd. If you leave the bag open, doesn't the bread become dry and hard? Doesn't that mean it lost it's moisture. Are you a complete idiot or you just play one in real life?
