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






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






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






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






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






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






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






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






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






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






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


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






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






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






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






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






17. 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.






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






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






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






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






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






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






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






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






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






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






28. 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)






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






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






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






32. 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






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






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






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






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






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






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






39. Anything that has mass and takes up space.






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






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






42. A subatomic particle that has a negative charge






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






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






45. 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






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






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






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






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






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