Across
- 2. one or more substances found before the arrow
- 4. changes in a property of matter that transforms and yields a new matter
- 5. the substances present at the end of the chemical reaction, they are found after the arrow
- 6. ________ is vaporization that occurs at the surface of a liquid and can occur at temperature below the liquid's boiling point
- 11. represents the direction of the chemical reaction; read as 'yields'
- 12. the extra kinetic energy in the ____ phase allows particles to partially overcome the attractions to other particles (thus the particles can slide pass each other)
- 13. The _________ of a liquid is the temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid.
- 14. The amount of energy required to change a substance from the solid phase to the liquid phase at its melting point is known as the __________.
Down
- 1. is the total energy of a material's particles, including kinetic and potential energy
- 3. in this phase the particles are moving so quickly they overcome the attractive forces between them.
- 4. the law of ________ states that the mass of all substances that are present before a chemical change equals the mass of all the substances that remain after the change.
- 7. usually a reversible change in matter that does not yield no identity
- 8. The __________ is a force pushing down upon a liquid, keeping particles from escaping.
- 9. type of matter that has the greatest attraction between its molecules, has definite shape and volume
- 10. is the spreading of particles throughout a given volume until they are uniformly distributed.
