A helium balloon has a volume of 6.9 L at 28.5 °C and 1.00 atm pressure. The balloon rises to an altitude where the air pressure is 0.76 atm and the temperature is -21.0 °C. What is its volume when it reaches equilibrium at this altitude? (Note: Neglect tension forces in the material of the balloon.)

Answer #1

New volume, V2 = (P2/P1) (T2/T1) V1

V2 = (1/0.76) (252/301.5) x 6.9

V2 = 7.59 L
