What happens to the water in the small tube as the water in the test tube absorbs heat? Why do you think a small tube was used to observe the expansion of water?

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
