What would happen if the lid of a jar filled with helium gad was removed?

1 answer:

7 0

The helium would expand into the air of the room. Depending on how big the room is, and the amount of helium in the jar, it could cause damage to health. The only way this would happen is if the room was small and the jar was big.

I hope this helps!
