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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






17. 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.






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






19. 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.






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






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






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






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






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






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






26. 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.






27. 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)






28. 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






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






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






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






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






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






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






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






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






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






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






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






40. 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






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






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






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






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






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






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






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






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






50. Anything that has mass and takes up space.
