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 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






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






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






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






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






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






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






8. 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






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






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






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






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






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






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






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






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






17. Anything that has mass and takes up space.






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






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






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






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






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






24. 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.






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






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






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






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






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






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






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






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






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






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


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






36. A subatomic particle that has a negative charge






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






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






39. 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.






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






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






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






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






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






45. 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.






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






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






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






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






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