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 state of matter that has a definite volume but not a definite shape






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






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

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






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






6. A subatomic particle that has a negative charge






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






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






9. 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






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






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






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






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






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






15. 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.






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






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






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






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






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






21. 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.






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






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






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






25. Anything that has mass and takes up space.






26. 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.






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






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






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






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






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






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






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






34. 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)






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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