(1) Given the condensation temperatures for the four main components of planets (metal, rock, ice and gas) and an indication of the temperature in various parts of the solar nebula disk, be able to identify and explain which components you would expect to condense into solid form at various locations in the solar system.
Hydrogen and helium gas make up about 98% of the solar nebula's mass and does not condense. Therefore most of the nebula remains gaseous. The other materials can, however, condense into solid materials whenever the temperature allows. Close to the sun, where temperatures can reach and upwards of 1600 K, it's too hot for anything to condense down to anything other than gas. Near Mercury's orbit, it is possible for somethings to condense into tiny, solid particles, but the other types of rock and hydrogen compounds remain gaseous.(500-1300K) Around Venus, Earth, and Mars more types of rock and metal condense. Around the asteroid belt area, temperatures are perfect for dark, carbon-rich minerals to condense along with minerals containing small amounts of water. The frost line (-150 K) marks the boundary where it is possible for hydrogen compounds to condense into ices. This line is between the orbits of mars and jupiter. Everything beyond that is made of mostly metal and ice, since it is more easily formed in that area of the solar system.
