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






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






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






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






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






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






7. 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.






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






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






10. A subatomic particle that has a negative charge






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


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






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






14. 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.






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






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






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






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






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






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






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






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






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






24. Anything that has mass and takes up space.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






46. 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.






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






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






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






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