Question

Why can a small tank of helium gas fill so many balloons?

Answer 1

Answer: one of my favorite question

Explanation:The tank can hold enough helium because the gas in the tank is under tremendous pressure. Gas will contract under high pressure, and expand under low pressure. When the helium goes into the balloons, it occupies much more space because there is less pressure in the balloons than in the tank.]

Answer 2

The Helium in the tank is under tremendous pressure so as per boules law PV = constant nd hence The gas exapands nd increase in volume nd hence it can fill soany baloons
