Across
- 1. / The basic SI unit of energy.
- 5. / A chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature
- 6. / The change in the state of matter from the gas phase to the liquid phase. It is the reverse of vaporization
- 7. Chadwick / Discovery of the neutron
- 10. / The transfer of energy that results from the difference in temperature between a system and its surroundings.
- 11. / Occurs in the stars. The gaseous state of matter that contains numbers of electrically charged particles
- 13. / The process through which a substance changes from a liquid to a solid. It becomes sufficiently cold
- 14. Formula / stating the simplest ratio of atoms in the molecule
- 15. / A chemical reaction that releases energy through light or heat.
- 16. / Is defined as a phase transition from the liquid state to the gas state, usually occurs when a liquid is heated to a certain point
- 18. / The quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
Down
- 2. / The transition from the solid phase to the gas phase without passing through an intermediate liquid phase
- 3. / Rigid and possesses a specific shape
- 4. / A process by which a substance changes from the solid phase to the liquid phase
- 6. / The study of the composition, properties, and interactions of matter that is based on observation and experimentation
- 7. Dalton / Revived the atomic Theory 1807
- 8. / The process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.
- 9. Change / The term phase transition is most commonly used to describe transitions between solid, liquid, and gaseous states of matter
- 12. / flows and takes the shape of its container
- 17. / Takes up the shape and volume of its container
