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






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






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






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






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






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






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






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






9. 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






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






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






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






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






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






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






16. Anything that has mass and takes up space.






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






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


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






20. 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.






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






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






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






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






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






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






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






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






29. 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.






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


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






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






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






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






35. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






49. A subatomic particle that has a negative charge






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