Hydrogen was first used but was generally replaced with helium because of it's flammability.
Helium
which type of gases are used in titanic
helium
oxygen air
It's lighter than air so the balloons float.
Hot air ships, also known as hot air balloons, were successful in terms of demonstrating manned flight. The first successful hot air balloon flight was achieved by the Montgolfier brothers in 1783. However, hot air balloons are limited in terms of speed, distance, and control compared to other forms of air transportation.
To inflate means to fill something with air or gas in order to make it expand or become larger and more firm. This process is commonly used in activities like inflating balloons, tires, or air mattresses.
no its oxygen cause we take the air out of the air and put it in a can
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
because of air exerting pressure from afar it is possible to fill the bag with air in first breath if blown from near it may take around 70 breaths to fill the bag.

Helium is commonly used to fill balloons. It is non-flammable and lighter than air, allowing balloons to float.
