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






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






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






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






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






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






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






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


9. 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






10. A subatomic particle that has a negative charge






11. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






27. Anything that has mass and takes up space.






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






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






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






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






32. 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.






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






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






35. 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)






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






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






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






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






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


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






42. 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.






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






44. 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.






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






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






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






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






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






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