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 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.






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






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


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






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






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






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






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






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






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






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






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






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






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






15. 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.






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






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






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






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






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






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






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


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






24. A subatomic particle that has a negative charge






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






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






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






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






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






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






31. Anything that has mass and takes up space.






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






33. 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.






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






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






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






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






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






39. 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






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






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






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






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






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






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






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






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






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






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






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