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






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






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


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






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






6. 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






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






8. 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)






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






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






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






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






13. Anything that has mass and takes up space.






14. 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.






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






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






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






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






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






20. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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


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






46. A subatomic particle that has a negative charge






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






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






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






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