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






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






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






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






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






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






7. Anything that has mass and takes up space.






8. 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)






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






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






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






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






13. 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.






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






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






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






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






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


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






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






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






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






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






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






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






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






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






28. 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






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






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






31. A measure of the amount of matter in an object; a fundamental property of an object that is not affected by the forces that act on the object - such as the gravitational force.






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






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






34. 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.






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






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






37. The tendency of an object to resist being moved or - if the object is moving - to resist a change in speed or direction until an outside force acts on the object






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






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






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






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






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






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






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






45. A subatomic particle that has a negative charge






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






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






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






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






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