SAT Subject Test: Chemistry Vocab

Subjects : sat, science, chemistry
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 layer of gasses surrounding the earth - A unit of pressure (1 atm = 760mm of Hg or torr)






2. A liquid that will conduct and electric current






3. A device used to accelerate charged particles to high energies for bombarding the nuclei of atoms






4. Loss by a substance of its water of hydration on exposure to air at ordinary temperatures






5. A compound whose basic structure contains the benzene ring; it usually has an odor






6. Streams of electrons given off by the cathode of a vacuum tube






7. A temperature scale divided into 100 equal divisions and based on water freezing at 0 degress and boiling at 100 degrees






8. A substance composed of two or more metals - which are intimately mixed; usually made by melting the metals together






9. A relatively weak force of attraction between polar molecules; a component of van der Waals forces






10. Isotope of hydrogen - sometimes called heavy hydrogen - with an atomic weight of 2






11. Heat content of a chemical system






12. Covalence in which both electrons in a pair come from the same atom






13. The temperature at which the vapor pressure of a liquid equals the atmospheric pressure






14. Having no definite crystalline structure






15. Chemical reaction that results in the giving off of heat






16. The process of first vaporizing a liquid and then condensing the vapor back into a liquid - leaving behind the nonvolatile impurities






17. Capable of being drawn into a thing wire






18. Containing no water






19. High=speed - negatively charged electrons emitted in radiations






20. The use of radioactive carbon-14 to estimate the ages of ancient materials - such as archaeological or paleontological specimens






21. Top number on periodic table - The number of protons in the nucleus - The number of electrons in an atom






22. A change by which an element takes the place of another element in a compound






23. Temperature measured on the absolute scale - which has its origin at absolute zero






24. Unit for expressing the kinetic energy of subatomic particles; the energy acquired by an electron when it is accelerated by a potential difference of 1 volt






25. Suspension of fine particles or droplets of one liquid in another - the two liquids being immiscible in each other; surrounded by an emulsifying agent






26. One of the "building blocks" of proteins; contains one or more NH2- groups that have replaced the same number of hydrogen atoms in an organic acid






27. The numerical expression of the relative strength with which the atoms of an element attract valence electrons to themselves; the higher the number - the greater the attraction






28. An ion or particle that has a negative charge and thus is attracted to a positively charged anode






29. Temperature scale that has 32 as freezing point and 212 as boiling point






30. The difference in potential between an electrode and the solution in which it is immpesed
