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.

18. The highest temperature at which water vapor condenses out of the air






19. Substance that takes water from another substance






20. Process for converting atmospheric nitrogen into compounds






21. Bonding accomplished through the sharing of electrons so that atoms can fill their outer shells






22. The smallest particle of an element that retains the properties of that element and can enter into a chemical reaction






23. Capacity to do work






24. A cell in which electrolysis is carried out






25. The breaking down of a compound into two or more simpler substances






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






27. Colloidal substance that forms a film about the particles of two immiscible liquids so that one remains suspended in the other






28. Heat content of a chemical system






29. Breaking down of a compound into simpler substances or constituent elements






30. Containing no water






31. The energy needed to break a chemical bond and form a neutral atom






32. The minimum energy necessary to start a reaction






33. Shows only the simplest ratio of the number and kids of atoms






34. The process of separation of a solution by diffusion through a semipermeable membrance






35. Chemical reaction that results in an absorption of heat






36. The adhesion (in an extremely thing layer) of the molecules of gases - of dissolved substances - or of liquieds to the surfaces of solid or liquid bodies with which they come into contact






37. Forms of the same element that differ in their crystalline structures






38. A substance composed of elements chemically united in definite proportions by weight






39. A substance that speeds up or slows down a reaction without being permanently changed itself






40. The layer of gasses surrounding the earth - A unit of pressure (1 atm = 760mm of Hg or torr)






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






42. Substance that - when added to a solution - makes changing the pH of the solution more difficule






43. Usually - a strong base - such as Sodium hydroxide - potassium hydroxide






44. In metallurgy: a substance that helps to melt and remove the solid impurities as slag






45. A nonmetallic oxide that - when placed in water - reacts to form an an acid solution






46. Ethyl alcohol that has been poisoned in order to produce a cheaper alcohol for industrial purposes






47. A chance that alters the atomic structures of the substances involved and results in different properties






48. A unit of heat; the amount of heat needed to raise the temperature of 1 gram of water 1 degree on the celcius scale






49. Residual radioactivity from an atmospheric nuclear test - eventually settles on the surface of the earth
