Every morning I fill up a glass with water and put it on my desk. I drink about a 1/4 of it. Then, sometimes it sits there the rest of the morning, like if I'm not working at my desk or I choose to drink coffee instead. After lunch, when I get fresh water, I've noticed that there are little bubbles in the water. Right now, the water has been sitting for an hour and there's no bubbles. But, I know there will be later. What's going on?

I would imagine this: There are gases (like carbon dioxide, oxygen, etc)
dissolved in water. When water is heated, these gases are less soluble
in the water. When you boil water, the bubbling is dissolved gases being
released. So I would say that leaving a glass of water siting out
lets the water "warm" up and those bubbles are bubbles of oxygen, carbon
dioxide, etc being released. No, you're not boiling the water by leaving
it out...the gases are just less soluble at the warmer temperature

Tap water contains disolved gasses, particularly oxygen and nitrogen. Unlike solides, the solubility of gasses decreases as temperature increases. Therefore, as your glass sits and warms, the gasses come out of solution and form little bubbles.
Pop goes flat when you take it out of the fridge, and let it get warm and the put it back in the fridge. As it gets warm, the gasses come out of solution. When you cool it, then, the gasses don't dissolve back in very quickly (it's a slow process) and then you have flat pop.

selfmade Yogurt a million quart milk a million/4 cup yogurt (from keep) a million/2-a million cup nonfat dry milk powder (powdered milk) a million. combine liquid milk and powdered milk in a pot, positioned on range at medium putting. 2. preheat oven or toaster oven to "heat" putting (a hundred-a hundred and fifty ranges F). 3. as quickly as milk threatens to boil over, eliminate from range and cool (in ice tub if needed) so as that the pan isn't too warm to touch. 4. combine milk and yogurt in an extremely sparkling tupperware field, cover field. 5. set field in pre-heated oven, go away for style of 6 hours. 6. your yogurt might desire to be advantageous and thick-- now keep it interior the refrigerator for as much as two weeks. 7. word: rather of warmth oven, you ought to use a sunny outdoors spot throughout summertime. 8. in iciness, you could set the field by technique of a radiator or wood range. 9. the acceptable incubation temperature is one hundred fifteen ranges F, plus or minus 10.

the bubbles that you see is air that is trap in the water that is coming up it it burst the air will be removed. When you are pouring that water in the cup the water was mixed with air
