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






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






3. Anything that has mass and takes up space.






4. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






24. A subatomic particle that has a negative charge






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






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






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






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






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






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






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


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






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






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






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






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






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






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






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






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






42. 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)






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






44. 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






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






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






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






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






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






50. 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.
