[SOLVED] Adiabatic Hot-Air Balloon Rising Question
A large research balloon containing 2.00 x 10^3 m^3 of helium gas at 1.00 atm and a temperature of 15.0 degrees Celsius rises rapidly from ground level to an altitude at which the atmospheric pressure is only 0.900 Atm. Assume the helium behaves like an ideal gas and the balloon's ascent is too rapid to permit much heat exchange with the surrounding air.
pv = nRT
I am not sure what to do, I tried using
[tex] P_1*V_1 = P_2*V_2 [/tex], but this doesn't work - I think it is becausethe temperature isn't quite constant. (The next question asks for the change in T)
Does anyoine have any ideas?
