- 2. the hotness and coldness of a substance stated in degrees; a measure of the average kinetic energy of the particles of a substance
- 3. a charged atom or group of atoms cause by a charge imbalance which is produced by an unequal number of protons and electrons
- 5. a pure substance formed by chemically combining two or more elements
- 6. a fluid state of matter made of extremely hightemperature ionzed particles
- 9. Anything that has mass and takes up space; a physical substance
- 10. a material made of only one kind of element or compound; not a mixture
- 12. the amount of space that an object occupies
- 14. work is done when a force acts on a moving object in the same or opposite direction of its motion or when
- 16. a push or a pull of an object
- 18. the change in state from a gas directly to a solid caused by removing energy
- 19. is transferred from one object to another
- 21. the change in state from liquid to a gas cause by adding energy
- 25. the change from one pure substance to another by the rearrangement of atoms in a chemical reaction
- 29. a change of matter that doesn't alter its chemical identity

Down
- 1. the attractive force between any two objects based on their masses
- 4. a change of one element into another element by changes occuring in the nucleus of the absorb rays or particles
- 7. the physical form of matter described by its physical characteristics. The state of a pure substance largely depends on its temperature. Matter can be a solid,liquid,gas,or plasma. Phase of matter is another term for state of matter
- 8. scientific law that states that matter and energy cannot be created or destroyed but can only transfer between objects or transfrom to a different form
- 9. the change of state from a solid to a liquid at the melting point is caused by adding energy
- 11. the change in state from a solid directly to a gas cause by adding energy
- 13. the change in state from liquid to a solid cause by removing energy
- 15. the change in state form a gas to a liquid cause by removing energy
- 17. the change of state from a liquid to a gas at the boiling point
- 20. the smallest neutral particle of an element that retains the characteristics of that element
- 22. a fluid state of matter in which the particles are free to move but are held close to each other
- 23. a fluid state of matter in which particles move so fast and are so far apart as to have little interaction with each other
- 24. the force of gravitational attraction between an obects mass and its resident planet
- 26. a pure substance made of only one kind of atom
- 27. two or more chemically bonded atoms molecules can be made of just one kind of element or a combination of elements
- 28. the change of state from a liquid to a gas below the boiling point but above the freezing point
