MATTER
Across
- 2. - a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.
- 3. - two or more different substances are physically mixed, but not chemically combined.
- 6. - refers to whether a compound will burn when exposed to flame. Again, burning is a chemical reaction commonly a high-temperature reaction in the presence of oxygen.
- 7. - It is the quality of being hot. Substances respond to heating in different ways. Some warm-up very quickly just to increase temperature.
- 10. - is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated.
- 11. - is a gas whose atoms have lost some or all of their electrons - it is a gas of ions and electronsa plasma has no definite shape or volume
- 13. - the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates.
- 16. - The ability of matter to be bent or hammered into thin sheets without falling into pieces.
- 17. - particles of a solid suspended by shaking or stirring in a liquid or gas.
- 18. - a single-phase system; are formed when solids, liquids or gases dissolve in a solvent.
- 19. - is a technique used to separate out homogenous mixtures where there is one or more dissolved solids.
Down
- 1. - is a separation process which uses the action of centrifugal force to promote accelerated settling of particles in a solid-liquid mixture.
- 4. - It is the act of emitting radiation spontaneously.
- 5. - mixtures having a non-uniform composition containing two or more phase with definite boundaries between the phases. It refers to materials in which there are visible different parts.
- 8. - are formed by ionic bond or by the transfer of electrons/s between a metal and a nonmetal.
- 9. – elements that possesses the characteristics of both metal and non-metal.
- 10. - involves separating a dense, insoluble substance from a heterogeneous mixture.
- 12. - involves separating a mixture based on different sizes of components.
- 14. - consist of fine particles (the disperse phase) of one substance finely dispersed in another (the continuous phase).
- 15. -It is the degree to which a chemical substance can damage a living organism.
