A balloon is filled with helium at sea level. The volume was measured to be 3.1 liters at a pressure of 0.97 atmosphere. If the balloon is released, it drifts upward. At a height of 4 kilometers, the pressure is measured to be 0.61 atmospheres. What is the volume of the balloon

Question

anonymous · Answer

I think you can apply boyle's law which states that product of pressure and volume is a constant.
 p1*v1=p2*v2
 p1=.97atm
 v1=3.1L
 p2=.61
 v2=?
 do the math.
