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 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.






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






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






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


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






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






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






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






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






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






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






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






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






14. 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)






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






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






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






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






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






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






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






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






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






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






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






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






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






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






29. 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






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






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






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






33. Anything that has mass and takes up space.






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






35. 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






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






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






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






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






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






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






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






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






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


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






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






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






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






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






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