Question 11 if condensation was occurring during the ascent from 800 mb to 500 mb, the air parcel would have water vapor during the ascent

Lost water vapor during the ascent.

The water vapor present on the parcel will have condensed to form liquid water, after which the water will precipitate downwards on the surface of the earth. When the parcel once again starts to descend, the parcel will warm up and will once again become unsaturated.

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
