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


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






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






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






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






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






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






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






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






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






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






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






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






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


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






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






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






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






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






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






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






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






23. 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.






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






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






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






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






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






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






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






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






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






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






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






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






36. Anything that has mass and takes up space.






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






38. 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






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






40. A subatomic particle that has a negative charge






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






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






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






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






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






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






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






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