Water cannot fill the glass because
the glass is already ~lled with air. The "empty"
glass is full of air. So, air takes up space.
Air is a gas. It has no size or shape of its own but
will fill every space it can.
yes,a paper towel doesnt melt in salt water fastly as much as in fresh water.in fresh water it melts more fastly than in salt water.
A paper towel holds 2 pounds and 5 ounces of water.
Yes. The thicker the paper towel the more water it can absorb.
The water level in the glass probably looked lower than before the rolled paper towel was put in. If the amount of water was small and the paper towel was big enough, the water level could decrease or even be absorbed completely.
the paper towel sucks up some of the water but some sits on top of it, as the towel is saturated and cannot hold more water. Although it will not drip off unless there is to much and it can't be absorbed
Absorbency of a paper towel depends on its composition and structure, so it's different for each brand.
Take several folds of ordinary paper towel and get them good and moist. Lay several ordinary nails on the paper towel, keep the paper towel damp. In a day or two, there will be rust on the nails. Sprinkling salt on the paper towel will speed up the process even more, as will soaking the paper towel in salt water first. \
If it is in water it will start to become the same temprature as the water. But if it is on paper towel the air aroud itwill melt the ice cube.
Yes.
Adhesion.
It depends on how many drops are put on the towel and how big the paper towel is. If it is full size, and you put one small drop on it, the towel would soak it up. The water would not fill up the whole paper towel, but just a bit. If it was a really big drop, it would probably soak through the paper towel and onto the surface the paper towel is laying on.
The best paper towel to use when trying to clean up a greasy mess is Viva. You can wring out the water then clean with the same paper towel you were just using with out it having holes.
