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






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






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






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






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






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






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






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






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






10. Anything that has mass and takes up space.






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






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






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






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






15. 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.






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






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






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






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


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






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






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






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






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






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






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






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






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






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






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






32. 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






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






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






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






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






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






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






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






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






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






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






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


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






45. A subatomic particle that has a negative charge






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






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






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






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






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