Across
- 3. firm and stable in shape; not liquid or fluid
- 4. (heat of) the heat absorbed by a unit mass of a given solid at its melting point that completely converts the solid to a liquid at the same temperature: equal to the heat of solidification
- 5. the lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal
- 7. a substance made by mixing other substances together
- 9. the relationship between the pressure and volume of a gas at constant temperature; when volume increase, pressure decreases, ideal Gas Law.

- 12. a thing that is composed of two or more separate elements
- 14. a porous material is used to separate particles of different sizes
- 15. the direct solidification of a vapor by cooling; the reverse of sublimation
- 16. the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field that causes the flow of current
- 18. a law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature
- 20. (heat of) is temperature-dependent, though a constant heat of vaporization can be assumed for small temperature ranges and below
- 21. heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction
- 24. a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent)

- 29. the quality of something that can be shaped into something else without breaking
- 30. the continuous physical force exerted on or against an object by something in contact with it
- 32. a change from one state (solid or liquid or gas) to another without a change in chemical composition
- 34. cause (a substance) to be deposited in solid form from a solution
- 36. each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter
- 37. having a consistency like that of water or oil, i.e., flowing freely but of constant volume
- 38. physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy
