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






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






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






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






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






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






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






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






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






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






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






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






13. A subatomic particle that has a negative charge






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






15. Anything that has mass and takes up space.






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






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






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






19. 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)






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






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






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






23. 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






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






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






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






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






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






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






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

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






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






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






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






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






38. 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.






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






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






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






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






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






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






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






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






47. 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.






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






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






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