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






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






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






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






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






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






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






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






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






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






11. 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.






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


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






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






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






16. 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)






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






18. 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






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






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






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






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






23. Anything that has mass and takes up space.






24. 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.






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






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






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






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






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






30. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. A subatomic particle that has a negative charge






47. 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.






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






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


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