As we move from the center to the surface of the earth, we will observe a progressive decrease in density and temperature. Highest density is concentrated in the center, because of the confining force of gravity. WebA vertical 1.5-m-high and 3.0-m-wide enclosure consists of two surfaces separated by a 0.4-m air gap at atmospheric pressure.
