Question

Helium gas is used in filling weather balloons.

• A. True
• B. False

Answer 1

The correct option is A True

• Helium(He) is an inert gas having atomic number 2.
• Helium is lighter than air and has less density than it.
• Since it is less dense than air, we observe that the balloon starts rising upwards.
• Also, Its inflammable nature prevents the action of air and explosion.
• Therefore, Helium gas is used in filling weather balloons.

Hence, the given statement holds true.
