Spread positive vibes at venue with helium balloons

Balloons symbolize positivity and happiness. They can brighten up any occasion with a smile on every face. And that decides the opulence of any event! However, if you are planning to have a lavish wedding or a grandeur occasion, then you would need balloons on a very large scale. For this, you can contact big exporters who would provide you with options in balloons to suit your pocket.

Balloons have always been a part of our celebrations. Almost every child has had an innate liking for balloons and it is one of the cheapest toys one can buy. Balloons used to be traditionally just filled with air but after the introduction of helium balloons the entire scenario changed. The specialty of helium balloons is that it uses helium gas which being the lightest gas makes the balloons rise above the air. Before helium was used the balloons were filled with hydrogen but hydrogen is highly combustible and posed some serious risks, the worst incident noted in the history of aviation related to blimps was due to the use of this highly combustible gas to float the huge 813 foot aircraft in air.

Helium balloons in today’s world have multiple uses. Helium balloons can be used as decorative items, advertising, signs and even some high tech helium balloons are used by meteorological departments to analyze weather conditions. Blimp aircrafts are also a kind of helium balloon. The large body carries helium and is propelled with the help of an engine powering a huge fan rotor. Helium balloons can be found in various shapes, size and color. Helium balloons can be made of latex or foil and can be translucent, transparent or opaque.

By what percent has the volume of the helium-filled balloon decreased?

Two identical balloons are filled to the same volume, one with air and one with helium. The next day, the volume of the air-filled balloon has decreased by 4.2%. By what percent has the volume of the helium-filled balloon decreased? (Assume that the air is four-fifths nitrogen and one-fifth oxygen, and that the temperature did not change.)

Assuming the leaks in the balloons are also identical and that the pressure of the gases inside the balloons remain the same during the "leak," the amount of air lost in a given period of time will be proportional to the rate at which a gas leaves a balloon and inversely proportional to the square root of gas' average molar mass:
(ΔV1)sqrt(m1) = (ΔV2)sqrt(m2)

The average molar mass of the air would be the weighted average of the 2 primary gases in comprises:
m1 = (28 g/mol)(4/5) + (32 g/mol)(1/5) = 28.8 g/mol

(4.2)sqrt(28.8 g/mol) = (ΔV2)sqrt(4 g/mol)
ΔV2 = 11.3% decrease
