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






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






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






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






5. 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)






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






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






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






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






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






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






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






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






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






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






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






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


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






19. 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






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






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






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






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






24. 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






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






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






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






28. Anything that has mass and takes up space.






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






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






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






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






33. 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.






34. A subatomic particle that has a negative charge






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






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


37. 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.






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






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






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






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






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






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






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






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






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






47. 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.






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






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






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