Particles and Separating Techniques
Across
- 6. The state of matter in which a substance can flow and take the shape of a container. It has a fixed volume and cannot be compressed. The particles can move around each other. Shown as (l) in chemical equations.
- 8. The substance that remains in the filter paper during filtration.
- 10. The substance that passes through the filter paper during filtration.
- 16. The liquid in which a solute dissolves. In salt water, this liquid is the water.
- 17. The model that shows the arrangement and movement of particles in solids, liquids and gases.
- 19. Techniques to separate out substances from a mixture.
- 20. The ability of a solute to dissolve in a solvent.
- 21. The random movement of small particles suspended in a fluid.
- 23. The change of state from solid to liquid.
- 24. The spreading out of particles from an area of higher concentration to an area of lower concentration.
- 25. The state of matter in which a substance has a fixed shape and cannot flow or be compressed. The particles are close together in a regular arrangement. Shown as (s) in chemical equations.
- 26. The substance that dissolves in a solvent to make a solution. In salt water, this substance is the salt.
- 28. When something is squeezed or pressed together.
Down
- 1. The change of state from a liquid to a gas. It occurs throughout the liquid when it reaches the boiling point temperature.
- 2. The change of state from gas to liquid.
- 3. The change of state from liquid to solid.
- 4. The classification of a substance as solid, liquid or gas.
- 5. A physical change from one state of matter to another.
- 7. A technique used to separate substances based on their solubility in a particular solvent.
- 9. A technique to separate and collect a solvent from a solution.
- 11. The change of state from liquid to gas. It occurs at the surface of the liquid and can happen below the boiling point. It can be used as a method to separate a mixture.
- 12. When a soluble solid becomes mixed into a liquid to form a solution.
- 13. The state of matter in which a substance can flow and completely fill a container. It has no fixed shape or volume and can be compressed. The particles are far apart and move quickly in all directions. Shown as (g) in chemical equations.
- 14. A technique used to separate substances that are insoluble from those that are soluble in the solvent.
- 15. A change of state from solid to gas.
- 16. When the maximum amount of solute has dissolved in a solvent.
- 18. A mixture of two or more substances in a liquid, formed when a solute dissolves in a solvent. Salt water is an example.
- 22. The amount of space that a substance or object occupies.
- 27. A measurement of how closely packed the particles are in a substance.
