Aweather balloon is inflated to a volume of 27.2 l at a pressure of 753 mmhg and a temperature of 30.9 ∘c. the balloon rises in the atmosphere to an altitude where the pressure is 395 mmhg and the temperature is -15.9 ∘c. assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

By idea gas equation we can say

here P = pressure

V = volume

n = number of moles

R = Avagadro gas constant

T = temperature

So from above expression you can see that for constant number of moleswe can say

So finally the volume will be 43.9 L

nah.   i'm just sleepy.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
