Question

an empty metrological balloon weighs 100 N.It is filled with 20 cubic metres of hydrogen.How much maximum contents the balloon can lift besides its own weight?​

Answer 1

Answer:

Mass of the air displaced =4190.47×1.2=5028.56 kg

No. of moles of helium in the balloon =

RT

PV

=

0.082×300

1×4190.47×10

3

=170344

Mass of helium =4×170.344×10

3

g=681.376 kg

Mass of filled balloon =681.376+100=781.376 kg

Payload = Mass of air displaced − Mass of filled balloon =5028.56−781.376=4247.184 kg.

Answer 2

Answer:

1. Due to the increase in pressure the density increases because, Due to the heavy air, a filled balloon will weigh a little heavier than a deflated balloon

• The correct mass of the inflated balloon was there- fore 1.55 + 6.75 = 8.30 g. Since the rubber itself had a mass of 1.30 g, the air inside the balloon had a mass of 7.00 g. This is slightly larger than the mass of the displaced air since the air inside the balloon was at a proportionally higher pressure.
• List all of the variables given. Mass of balloon = 80 kg. Volume of balloon = 1200 m3 Density of Helium = .18 kg/m3 Density of Air = 1.3 kg/m3Determine the the total mass that can be lifted by the helium balloon. Mass lifted = mass of the volume of fluid displaced. Mass = (1200 m3)( 1.3 kg/m3) Mass = 1560 kg.
