CSET Subject 2: Science

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

47. Is the smallest unit of an element that still has the properties of that element.






48. That matter cannot be created or destroyed; it simply changes form.






49. The Moon is between the Earth and the Sun.






50. The measure of the kinetic energy in a substance's molecules. Simply - temperature is atomic motion.
