- 1. comes from the greek word amorphous when this is cleaved or broken they produce fragments with irregular often curved surfaces and they have poorly defined patterns and amorphous is a translucent solid is called a glass.
- 5. is a measure of how much a liquid resists flowing freely and example would be honey and he said that it is more viscous than a liquid.
- 6. are made of electrically charged particles, hot ionized gas where electrons break free.
- 9. happens on a molecular level. A change in color shows obvious chemical change at the substance has undergone.
- 14. is a state of matter of a dilute gas of boson school to temperatures close to absolute zero or the lower limit of the thermodynamic scale.
- 16. are very easy to break apart and cannot hold their own shape because their particles are quite close to each other.
- 19. solids is held together by the same kind of forces that hold liquids together this force is the weakest among the types that hold solids together.
- 24. temperature of a substance is a temperature at and above which vapor of the substance cannot be liquefied gas particles move very quickly because of the empty space surrounding them, they do not have a definite shape or volume.
- 26. is a phase change at converts liquid into gas.
- 27. accounts for the surface tension of a liquid. It is the tendency for the same kind of particles to be attracted to one another.
- 28. is a process by which water is converted to its gaseous form from its liquid form.
- 30. can be thought of as a very thin layer of particles that are more strongly attracted to each other then they are to the particles surrounding them.
Down
- 2. is defined as a change of phase from one form to another which is affected by temperature pressure and energy.
- 3. solids are held together by covalent bonds these are the strongest kind of forces holding solids together they have extremely high melting points and most of them do not melt at all they decomposed before melting.
- 4. is the process of changing to gas solid without passing through its liquid phase.
- 7. pressure is the pressure required to liquefy glass at its critical temperature.
- 8. is a change of gas into its liquid form.
- 10. is a change of phase from liquid to solid.
- 11. is a distinctive form of a substance.
- 12. is a phase change from solid to liquid to the application of heat.
- 13. is the process of a liquid to easily vaporize at normal temperatures but some highly volatile solids may sublime at normal room temperature.
- 15. have distinctively flat surfaces or faces the faces intersect at angle that are characteristics of a substance. It has a distinctive pattern when an ionic crystal is cleaved or broken it produces new faces that is still flat and intersects at the same angle as those in the original crystal.
- 17. is a process of changing solid to gas without directly passing through its liquid phase.
- 18. changes the color of the petals of a flower gives other plants abused enjoying nutrient rich water from the soil up to the stem and into the leaves.
- 20. involves the physical properties of a substance including color, volume, shape, and phase changes.
- 21. the pressure exerted by the vapor / liquid in a closed container .
- 22. solids are held together by metallic bonds which involve electrons sharing throughout the body of the metal it has a wide range of melting points though almost all melt above room temperature this type of solid ranges from soft to hard.
- 23. accounts for the capillary action when a liquid is drawn up into a very narrow tube they're also attracted to the particles that make up the container holding the liquid.
- 25. solids are held together by ionic bonds these much stronger than the ones in molecular solids they have high melting points and are described to be hard they are non conductors of electricity.
- 29. point in order for a liquid to be converted to gas the temperature must be raised.
