Gas encompass density or not
Explain in brief that the gas encompass density or not?
Expert
Gas, and also everything in the globe consists of density, although some densities are not either too high or too low to be detected, examined or measured through the human eye nor the technological gadgetry designed and utilized by the scientists for that particular purpose.
