The answer is bhope this

C) the increase in atmospheric pressure pushes the walls of the balloon outward thus making it  is the answer.hope i you.

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
