CSET Subtest II: Science -Chemistry - Physics - Astronomy

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.
1. The mechanical energy that a body has by virtue of its motion






2. Kinetic Energy of molecular motion






3. Mass per unit volume of a substance.






4. A form of matter that flows - has constant volume - and takes the shape of its container but cannot be compressed.






5. A starlike object that may send out radio waves and other forms of energy






6. A metric unit of length equal to one thousandth of a meter






7. An immense cloud of gas (mainly hydrogen) and dust in interstellar space






8. A heavy odorless colorless gas formed during respiration and by the decomposition of organic substances - CO2






9. Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune






10. A property of some materials in which there is a force of repulsion or attraction between certain like and unlike poles.






11. A physical property that describes matter as a solid - liquid - or gas






12. A metric unit of length equal to 1000 meters (or 0.621371 miles)






13. The total kinetic and potential energy of all the particles in a substance.






14. Tending to move toward a center

16. A charged atom or group of atoms formed by the gain or loss of electrons.






17. A chemical reaction in which a compound is broken down into simpler compounds or elements.






18. The flow of electrons....Direct Current DC flows in one direction and Alternatin Current AC periodically reverses the direction of flow.






19. Occurs whent the fission on one atom causes the fission of other atoms






20. A negatively charged sub atomic particle; located outside the atomic nucleus Forms a cloud around the atomic nucleus. Electron movement constitutes electrical current.






21. The frequency of a sound wave






22. A chemical change in which a substance combines with oxygen - as when iron oxidizes - forming rust.






23. A condition where accelerating forces precisely offset one another.






24. A proposed scientific explanation for a set of observations






25. The principal that the laws of physics are the same for any tow observers - whatever their relative motion.

27. The science of the substances that make up our world.






28. (physics) the force of attraction between all masses in the universe






29. Like the sun - these are composed of large masses of hydrogen pulled together by gravity. - form out of interstellar gas clouds - large cold could of H2 molecules and dust collapses and fragments Very far away






30. Nuclear reaction - small element atom fuses to form element with large atoms releasing large amounts of energy - elements coming together to make bigger atoms






31. (astronomy) a relatively small extraterrestrial body consisting of a frozen mass that travels around the sun in a highly elliptical orbit It glows with a prominent tail when its orbit brings it near the sun.






32. The process of decomposing a chemical compound by the passage of an electric current.






33. The most familiar of all liquids.






34. The quantity of matter; the measure of inertia






35. Compounds that form hydrogen ions when dissolved in water






36. German physicist whose explanation of blackbody radiation in the context of quantized energy emissions initiated quantum theory (1858-1947)






37. The law that states that for a fixed amount of gas at a constant pressure - the volume of the gas increases as the temperature of the gas increases and the volume of the gas decreases as the temperature of the gas decreases


38. A star that ejects some of its material in the form of a cloud and become more luminous in the process






39. The process of producing a chemical compound usually by the union of simpler chemical compounds.






40. The temperature below which a liquid turns into a solid






41. A huge group of single stars - star systems - star clusters - dust - and gas bound together by gravity






42. A value that indicated the acidity or alkalinity of a solution on a scale of 0-14 - based on the proportion of H+ ions. - p - otential of H- ydrogen






43. A cooler darker spot appearing periodically on the sun's photosphere

45. The upward force on an object immersed in a fluid.






46. The time required for one half of the atoms of a radioisotope to emit radiation an decay products






47. Energy stored due to an object's position or arrangement






48. All objects in the universe attract each other through gravitational force. Size of force depends on mass and distance






49. Energy may be changed from one formto antoher but it cannot be created or destroyed






50. Travels around the earth each month.
