A balloon has a volume of 10,500 liters and the tempature is 15 C. If the temp tire were - 25C what would the volume of the balloon be?

A-12,194L

B - 9,042L

Given an initial volume of 10,500 liters and initial temperature of 15 C, final temperature of - 25 C, and assuming that the gas inside the balloon is an ideal gas:

Ideal Gas Law:

nRT = PV

assume that the number of moles and pressure are constant, the equation becomes

V/T = constant

V1/T1 = V2/T2

Substituting given conditions, solve for V2:

10,500L / (15+273) = V2 / (-25 + 273)

V2 = 9041.67 L
