Day 2

4. point/the point at which materials changes from a solid to a liquid
7. a liquid turns into a gas
9. The process in which solid substances are converted into liquids by adding heat
12. and stable in shape; not liquid or fluid.
14. process in which liquid state changes into the vapor state
16. reaction/a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products
17. point/the temperature at which its vapor pressure is equal to the pressure of the gas above it
18. type of matter with specific properties that make it less rigid than a solid but more rigid than a gas
20. distinct period or stage in a series of events or a process of change or development.
21. heated matter – so hot that the electrons are ripped away from the atoms forming an ionized gas

1. anything solid turns into a gas without first becoming liquid
2. a liquid becomes a vapor by touching a hot surface
3. process in which something changes from liquid to solid as the temperature becomes lower.
5. property/a characteristic of a substance that can be observed or measured without changing the identity of the substance
6. solid whose atoms are arranged in a "highly ordered" repeating pattern
8. property/a characteristic of a particular substance that can be observed in a chemical reaction
10. point/the exact temperature at which a liquid becomes a solid
11. process where water vapor becomes liquid
13. substance that is in a gaseous, or vaporous, state of matter
15. change/a change of materials into another, new materials with different properties and one or more than one new substances are formed
19. measure of how quickly a specific material is capable of catching fire and burning.
