:It could be due to the depressurising gas in the aerosol being very cold due to adiabatic expansion.
12.
A third way to compute the entropy change involves a route consisting of reversible adiabatic expansion followed by heating.
13.
In an independent work, T . Finkelstein also assumed adiabatic expansion and compression spaces in his analysis of Stirling machinery
14.
Key steps are : ( 1 ) adiabatic expansion of power and cooled moist air from water and hot dry air:
15.
Adiabatic expansion causes the gas ( with a low boiling temperature ) to rapidly cool on exit from the aerosol applier.
16.
:: I've always understood that the main function responsible for the lapse rate is the adiabatic expansion / contraction of the circulating atmosphere.
17.
The adiabatic expansion is in a higher pressure range than that of the compression because the gas in the cylinder is hotter during expansion than during compression.
18.
For simplicity you can neglect the effect of adiabatic expansion on temperature of the air in the cave . talk ) 21 : 30, 24 October 2015 ( UTC)
19.
Nitrogen decompression is more protective of enzymes and organelles than shearing action that generate heat, the nitrogen decompression procedure is accompanied by an adiabatic expansion that cools the sample instead of heating it.
20.
For example, if a container filled with water vapour at slightly below the saturation pressure is suddenly cooled, perhaps by adiabatic expansion, as in a cloud chamber, the vapour may become supersaturated with respect to liquid water.
