A Helium filled weather balloon, when released, has a volume of 10.0 L at 27°C and a pressure of 663 mmHg. What Volume, in liters, will the balloon occupy at an altitude where the presure is 96 mmHg and the temperature is 30°C?
Use p1V1/T1 = p2V2/T2 where p is pressure, V is volume and T is absolute temperature (i.e. 27°C must become 300K and 30° must become 303K)
.
