Therefore, at sea level, air is 784 times less dense than water. Expressed in another way, a volume of air at sea level has 0.1275% of the density of the same volume of water. Dirt is about 2.5 times the density of water.
Penicillium (/ËpÉnÉªËsÉªlÉªÉm/) is a genus of ascomycetous fungi of major importance in the natural environment as well as food and drug production.
