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 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.






2. 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






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






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






5. A subatomic particle that has a negative charge






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






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






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






9. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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


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






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






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






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






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






29. 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)






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






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






32. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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