Water-bottle rockets are made by adding water to a bottle and pumping air
into it. The flight time and height depend on the shape and the size of the bottle and the amount of
water and air you pump into it. Some of the air that is pumped into the bottle dissolves in the water.
Which of the following choices best describes this event?
a. | molecular change | b. | physical change | c. | color
change |
