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 change of state from a gas to a liquid






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






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






4. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






21. Anything that has mass and takes up space.






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






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






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






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






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






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






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






29. 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






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






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






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






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

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






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






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






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






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






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






40. A subatomic particle that has a negative charge






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






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






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






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






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






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






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






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






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






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