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 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






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






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






4. 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.






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






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






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






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






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






11. 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






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






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






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






15. A subatomic particle that has a negative charge






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






17. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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


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






32. 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.






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






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






35. Anything that has mass and takes up space.






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






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






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






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






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






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






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






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






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






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






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






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






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


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






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