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






2. A unit of geologic time that is longer than an epoch but shorter than an era.






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






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






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






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






7. Anything that has mass and takes up space.






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






9. The change of a substance from a liquid to a gas






10. A subatomic particle that has a negative charge






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


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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






27. 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)






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






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






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






31. 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






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






33. The mass of an atom expressed in atomic mass units






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






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






36. 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.






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






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






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






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






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






42. 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.






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






44. A measure of how hot (or cold) something is; specifically - a measure of the average kinetic energy of the particles in an object.






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






46. The amount of force exerted per unit area of a surface.






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






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


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






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