A weather balloon near sea level (101,323 Pa, 299.19 K) has a volume of 261.17 ft3. It is launched and ascends to a height of 105,200 feet (861.62 Pa, 229.10 K) before bursting. What was its final volume, in ft3?

2219.945

Explanation:

861.62/101.323 = 8.5

261.17 x 8.5 = 2219.945

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.

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
