Gaseous objects is a lecture about specific astronomical, chemical, and physical entities composed mostly of gases at least as detected. It is also a lecture as part of the radiation astronomy department series on object astronomy.

You are free to take this quiz based on gaseous objects at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{radiation astronomy resources}}, {{chemistry resources}}, and {{physics resources}} templates. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!
