How does helium balloons work?
Helium is a chemical element. Its atomic number is 2. Helium is lighter than air. Helium balloons float due to the "law of buoyancy". Helium is a gas at room temperature and has fewer electrons, protons, and neutrons than air. This makes helium lighter than air.
There are three types of buoyancy:
1. Negative buoyancy - It is when the immersed object is heavier than the fluid it is placed in.
2. Neutral buoyancy - It is when the weight of an immersed object is equal to the fluid it is in.
3. Positive buoyancy - It is when the immersed object is lighter than the fluid it is placed in, causing the object to float.
In this video, we explain the types of buoyancy and also the reason behind the higher pitch of voice when we inhale helium.
