A student has a job after school delivering flowers and helium balloons. The student noticed that the volume of the balloons differed depending on the time of the year. They had a greater volume during the summer months and appeared to lose volume during the winter months after arriving at the destination. The student know each balloon had the same amount of gas and the balloons had no leaks. The student wants to understand why this happens. What would be a good hypothesis using the student's understanding of gas laws?
A. Balloons lose air with time, so they will lose volume.
B. The pressure at the store is different than at the destination causing the volume of the balloon to change.
C. The volume of a balloon is dependent on the time of year. Summer balloons have greater volume than winter balloons.
D. When the gas in balloons is warm, the balloons will be larger than when the gas is cold,

i think   the answer is c hope i'm right

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
