The decrease in density in the outer atmosphere affects satellite orbits.
The decrease in density of the Earth's atmosphere with increasing altitude causes radar waves to bend as they propagate through the atmosphere.
The behaviour of ice, which floats on water, and of a few other substances are notable exceptions to the usual decrease in density upon melting.
According to the big-bang model, the universe expanded rapidly from a highly compressed primordial state, which resulted in a significant decrease in density and temperature.
The average diameter of cavities increased with dose from 10 to 20 dpa, with a corresponding small decrease in density.
Although our models do not consider these processes and only take a mild decrease in density into account, large effects for the xenolith can be anticipated, i.e. the xenoliths may start to float after an initial phase of sinking.
On the other hand, the CO2 mixing ratio is uniform but optical depth in the CO2 band decreases with height due to the decrease in density (i.e., fewer CO2 molecules; Fig. S3).
When the temperature is higher than 1650 °C or when the heating time is longer than 2 h, a decrease in density is observed.
Addition of Bi increased the density of nBG samples while a considerable decrease in density was observed for nanocomposites with GO incorporation.
The decrease in density of lightweight aggregate concrete (LWAC) leads to the economic savings in terms of structural design, transportation and handling costs.
The decrease in density of sensitive defects and the increase in stability of defects are believed to be the benefits brought by the optimized design.
