Answer
Decreases
Explanation:
density=p=mv
as we can see that when density is directly proportional to mass
One is that climatic weight is significantly decreased at high elevations, so a helium swell grows as it rises and in the end detonates. On the off chance that you swell an inflatable past its points of confinement at room temperature, it will split into little pieces up to around ten centimeters in length.
hence density will decrease until it will split into parts by blast
