a weather balloon has a volume of 2.57 L when filled with helium at 22.6°c at a pressure of 727.7 torr. what is the new volume of the balloon (in liters) if the balloon rises to a point where the air pressure is 476.6 tore and the temperature is 3.9°c
Homework Answers
P1V1 / T1 = P2V2 /T2
P1 = 727.7 torr = 0.96 atm
V1 = 2.57 L , T1 = 22.60C = 295.6 K
P2 = 476.6 torr = 0.63 atm , V2= ?
T2 = 3.90C = 276.9 K
V2 = (P1V1T2 / T1P2)
V2 = (0.96 x 2.57 x 276.9 / 295.6 x 0.63)
V2 = 640.45 / 186.23
V2 = 3.44 L
