How helium balloons work?
Let’s suppose that you empty out a 1-litre plastic soda bottle and putt the cap back on it, bind a string around it and with it dive down underneath profound end of a swimming pool. If you sit underwater maybe 10 feet deep, holding the string, the bottle that is full of air will have a burly craving to mount to the surface.
It acts exactly like a helium balloon that quickly ascends to the surface of water if you let go off the string .The grounds for this soda bottle’s desire to rise to the surface is water being a fluid,1-liter bottle displaces one liter of the fluid. Since the bottle and the air inside weighs less than the weight of water it displaces, the bottle drifts.
Same law of buoyancy works for Helium balloons. In the case of helium balloon that is held by a string floats in a “pool of air” and when you are standing in an open field you are standing miles deep at the bottom of “pool of air”. The helium balloon according to law of buoyancy displaces an amount of air and as long as the balloon along with the helium is lighter than air it displaces, the helium balloon will float in air.
It spins out that helium is extremely lighter than air though the variation is not as immense as between water and air but is significant enough. Nitrogen weighs around 1.2506 grams per liter while Helium weighs around 0.1785 grams per liter and as nitrogen is major component of the air we breathe, 1.25 grams is a fine estimate for the weight of a liter of air. This elucidates why airships and helium balloons are usually quite large as they have to displace a lot of air so as to float.
