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 conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure






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






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






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






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






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






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


8. A subatomic particle that has a negative charge






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






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






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






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






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






14. 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.






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






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






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






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






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






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






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






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






23. 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.






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


25. 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.






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






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






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






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






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






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






32. 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)






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






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






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






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






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






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






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






40. 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






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






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






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






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






45. Anything that has mass and takes up space.






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






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






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






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






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