**drwls**, Thursday, November 18, 2010 at 8:40amPV/T is constant. That means PR^3/T is also constant. T must be in Kelvin. If subscript "1" denotes sea level and "2" denotes the working altitude,

(0.03 atm)*(20m)^3/200K = (1.0 atm)*(R1^3)*/300K

Solve for R1

**Y0gi**, Thursday, November 18, 2010 at 8:52amOh ok sweetness! Thanks. Figured out the answer. That makes sence. The only thing I had seen wrong with the equation you put is that you would need to find the volume, which is

(4/3)ğr^3 not jut r^3. But still helped out so thanks =)
