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.

25. Spiral disk with several long arms.






26. An atom that has a different number of neutrons than its normal amount.






27. A bond in which on atom loses an electron to form a positive ion and the other gains an electron to form a negative ion - creating an electrostatic force which holds them together.






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






29. Occurs when chemical composition of a substance is altered.






30. This is the motion of objects emitting or reflecting sound waves changing their frequency.






31. H2O + CO2 --> CH2O + O2






32. That space and time are relative - not absolute concepts






33. Is a method of separating ions within a substance by passing electrical current through the substance

36. The capacity to work






37. Unless an object is moving in a vacuum - the object causes...






38. 1. the more massive either or both bodies are - the greater the gravitational force between them. 2. the further apart two bodies are - the lesser the gravitational force between them.






39. 1. by row 2. atomic number and mass increase as you move left to right and top to bottom






40. Is the process of storing energy through photosynthesis and later releasing it through respiration.






41. States that all of the Earth's continents at one time were joined as a single 'super - continent' called Pangaea. Over time - the continents drifted apart.
