this is a hard question...?

Question

a weather balloon is launched from the ground(pressure = 1*10^5Pa, temperature = 27degrees) with a volume of 2cm cube. what volume does the balloon have when it has reached a height of 20km above the ground(pressure = 2*10^4Pa, temperature = -28degrees)

Answer 1

since P1.V1 / T1 = P2.V2 / T2 ... u don't actually care about the altitude. so V2 = 8.88 cm^3 (btw those degrees are °C, °F ?? cuz u gotta take them to Kevin before using them)

1*10^5 Pa * 2cm^3 / 270 °K = 2*10^4 Pa * V2 / 240 °K
V2 = 8.88 cm^3

Answer 2

Nicky,Please get a life.P.s. I agree !!.
