Introduction To Matter

Subject : 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. A mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and that are suspended in liquid - solid - or gas






2. The change of a substance from one physical state to another






3. The state of matter in which the volume and shape of a substance are fixed.






4. A region around the nucleus of an atom where electrons are likely to be found






5. Describes something that occurs or repeats at regular intervals.






6. A measure of the size or region in three-dimensional space.






7. A nerve cell that is specialized to receive and conduct electrical impulses.






8. In a solution - the substance in which the solute dissolves.






9. The force that acts on the surface of a liquid and that tends to minimize the area of the surface.






10. A homogeneous mixture throughout which two or more substances are uniformly dispersed.






11. In physical science - an atom's central region - which is made up of protons and neutrons.






12. The ratio of the mass of a substance to the volume of the substance






13. One of the elements of Group 18 of the periodic table (helium - neon - argon - krypton - xenon - and radon); noble gases are unreactive.






14. A vertical column of elements in the periodic table; elements in a group share chemical properties






15. A property of matter that describes a substances ability to participate in chemical reactions






16. A measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe.






17. A substance made up of atoms of two or more different elements joined by chemical bonds






18. An atom that has the same number of protons (or the same atomic number) as other atoms of teh same element do but that has a different number of neutrons (and thus a different atomic mass)






19. The curve at a liquid's surface by which one measures the volume of the liquid.






20. The law that states that the volume of a gas is directly proportional to the temperature of a gas when pressure is constant


21. An element that is shiny and that conducts heat and electricity well.






22. The sum of the numbers of protons and neutrons in the nucleus of an atom.






23. A mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas.






24. The amount of a particular substance in a given quantity of a mixture - solution - or ore






25. The smallest unit of an element that maintains the properties of that element






26. A change of matter from one form to another without a change in chemical properties.






27. An element that conducts heat and electricity poorly and that does not form positive ions in an electrolytic solution.






28. The state of matter that has a definite volume but not a definite shape






29. A change that occurs when one or more substances change into entirely new substances with different properties






30. A unit of mass that describes the mass of an atom or molecule






31. The change of state in which a solid becomes a liquid by adding heat or changing pressure.






32. The ability of one substance to dissolve in another at a given temperature and pressure; expressed in terms of the amount of solute that will dissolve in a given amount of solvent to produce a saturated solution.






33. The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure






34. A subatomic particle that has a negative charge






35. One of the elements of group 17 of the periodic table






36. Anything that has mass and takes up space.






37. A sample of matter - either a single element or a single compound - that has definite chemical and physical properties.






38. A from of matter that does not have a definite volume or shape






39. The number of protons in the nucleus of an atom; the atomic number is the same for all atoms of an element






40. One of the elements of Group 1 of the periodic table






41. A substance that cannot be separate or broken down into simpler substances by chemical means






42. The resistance of a gas or liquid to flow.






43. One of the elements of group 2 of the periodic table






44. The process in which a solid changes directly into a gas (the term is sometimes also used for the reverse process).






45. A characteristic of a substance that does not involve a chemical change - such as density - color - or hardness.






46. A subatomic particle that has a positive charge and that is located in the nucleus of an atom; the number of protons in the nucleus is the atomic number - which determines the identity of an element.






47. Elements that have properties of both metals and nonmetals; sometimes referred to as semiconductors.






48. The physical forms of matter - which are solid - liquid - gas - and plasma.






49. A combination of two or more substances that are not chemically combined.






50. The law that states that the repeating chemical and physical properties of elements change periodically with the atomic numbers of the elements.
