Question:
When a balloon rises, the air pressure drops to half the air pressure at sea level p Pa The density of the air on the ground is rho kgm The temperature of the atmosphere and the balloon should be assumed to be constant, so that the product p V can be assumed to be constant.
a At what altitude is the balloon?
b What density rho does the air have at this altitude?
c What maximum climbing height will the balloon reach if it is filled with gas of density rho G to the volume V at sea level and then tightly closed? The mass of the solid balloon envelope is mB and that of the payload is mN The volume of the balloon envelope and payload can be neglected.
