  1. 1. - A change that affects one or more physical properties of a substance without altering its chemical composition.
  2. 5. - A mixture in which particles are dispersed throughout a liquid or gas but are not fully dissolved.
  3. 6. Substance - A material that has a constant composition and consistent properties throughout. Pure substances can be elements or compounds.
  4. 7. - A property of a material that allows it to be deformed or shaped, typically by hammering or rolling, without breaking.
  5. 10. - The basic units of matter that make up all substances. They consist of protons, neutrons, and electrons.
  6. 11. - A mixture that consists of visibly different substances or phases.
  7. 13. - A form of matter that has a uniform and definite composition.
  8. 14. - Anything that has mass and takes up space. It is made up of particles.
  9. 15. - The mass per unit volume of a substance, often expressed in grams per cubic centimeter (g/cm³).
  10. 18. - To mix a solid, liquid, or gas into a liquid to form a solution.
  11. 19. - The substance in which a solute is dissolved to form a solution, usually a liquid.
  12. 20. - A distinct, homogeneous form of matter, such as solid, liquid, or gas.
  13. 23. - The process by which vapor changes into liquid when cooled.
  14. 24. - A substance that increases the rate of a chemical reaction without being consumed in the process, allowing the reaction to occur more quickly or under milder conditions.
  15. 27. - The energy related to the temperature of a substance, often affecting physical and chemical changes.
  16. 28. - The process of forming solid crystals from a solution as it cools or evaporates.
  17. 29. - A substance formed when two or more different elements are chemically joined together.
  18. 33. - A type of mixture where one substance (solute) is dissolved in another (solvent), resulting in a homogeneous mixture.
  19. 34. - The energy released or absorbed during a physical or chemical change.
  20. 35. - Characteristics or traits of a substance that can be observed or measured, such as color, density, and boiling point.
  21. 36. - The point at which a solution can no longer dissolve more solute at a given temperature.
  22. 37. - A mixture that is uniform in composition and appearance throughout.
  23. 38. - A combination of two or more substances where each substance retains its own properties.
  24. 39. - The arrangement of protons, neutrons, and electrons in an atom, determining its properties and behavior.
  25. 40. - A process that results in the formation of new substances with different properties from the original substances.
  26. 42. - The ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.
  27. 43. - A physical separation method used to remove solid particles from a liquid or gas using a filter.
Down
  1. 2. - A process in which substances interact to form new substances with different properties.
  2. 3. - The substances formed as a result of a chemical reaction.
  3. 4. - A pure substance that cannot be broken down into simpler substances by chemical means.
  4. 8. - A representation of a substance using symbols for its constituent elements and numbers to indicate the ratio of atoms.
  5. 9. - The amount of solute present in a given volume of solution, usually expressed in molarity or percentage.
  6. 12. - An electron located in the outermost shell of an atom that can participate in forming chemical bonds with other atoms.
  7. 16. - The energy required to initiate a physical or chemical change.
  8. 17. - A characteristic of a material that enables it to be stretched into a wire without breaking.
  9. 21. - A measure of the amount of matter in an object, usually measured in grams or kilograms.
  10. 22. - The starting substances in a chemical reaction that undergo change.
  11. 25. - The process by which a liquid changes into a gas, often resulting in the formation of vapor.
  12. 26. - The process of changing the arrangement of atoms in a molecule during a chemical reaction.
  13. 30. - The principle that mass is neither created nor destroyed in a closed system during a chemical reaction or physical change.
  14. 31. - The smallest unit of a compound, made up of two or more atoms bonded together.
  15. 32. - The substance that is dissolved in a solvent to form a solution.
  16. 35. - A solid that forms and separates from a liquid mixture during a chemical reaction.
  17. 41. - A mixture where tiny particles are evenly distributed throughout another substance, but are not heavy enough to settle out.
