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






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






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






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






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






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






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






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






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






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






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






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






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






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






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


16. 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






17. 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.






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






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






20. 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)






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






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






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






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






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






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






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






28. Anything that has mass and takes up space.






29. 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.






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






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






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






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






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






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






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






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






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






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






40. A subatomic particle that has a negative charge






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






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






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






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






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






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






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






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


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






50. 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
