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






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






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






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






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






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






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






8. Anything that has mass and takes up space.






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






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






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






12. 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.






13. 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)






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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


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






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






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






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


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






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






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






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






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






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






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






45. 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.






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






47. 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.






48. 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






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






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