Question

13 multiple choice 4 points the process in which a gas cools and its molecules stick together to form liquid particles is called. condensation. depression. evaporation. sublimation. 14 multiple choice 4 points thinking about the formation of the solar system, what trend in composition would you expect to see from the inside to the outside of the asteroid belt? asteroids with hydrogen and carbon compounds, progressing toward asteroids made primarily of iron and silicates. iron asteroids progressing more toward ones with silicates. rockier asteroids progressing toward ones with more hydrogen and carbon compounds. asteroids with hydrogen and carbon compounds progressing toward asteroids made primarily of ice. 15 multiple choice 4 points

Explanation:

1. For question 13: Condensation is defined as the phase change where a gas cools and forms liquid particles as its molecules stick together, matching the description.
2. For question 14: In the asteroid belt, closer to the Sun (inside), temperatures are higher, so only high-melting-point materials like iron and silicates could condense. Further out (outside), lower temperatures allowed more volatile materials like hydrogen and carbon compounds to exist in asteroids, creating a trend from iron/silicate-rich to hydrogen/carbon-rich asteroids moving outward.

Answer:

1. A. condensation.
2. A. Asteroids with hydrogen and carbon compounds, progressing toward asteroids made primarily of iron and silicates.
