- 2. : The force of gravitational attraction between an object's mass and its resident planet.
- 4. : A fluid state of matter in which the particles move so fast and are so far apart as to have little interaction with each other.
- 7. : The change of state from a liquid to a gas at the boiling point.
- 8. : A pure substance made of only one kind of atom.
- 13. : A fluid state of matter in which the particles are free to move but are held close to each other.
- 14. substance : A material made of only one kind of element or compound; not a mixture.
- 15. : A physical combination of two or more substances.
- 19. : The change of state from a solid to a liquid at the melting point that is caused by adding energy.
- 20. : The smallest neutral particle of an element that retains characteristics of that element.
- 23. : The hotness or coldness of a substance, stated in degrees; a measure of the average kinetic energy of the particles of a substance.
- 25. : The change in state from a liquid to a gas caused by adding energy.
- 27. : A push or a pull on an object.
- 30. : The change in state from a solid directly to a gas caused by adding energy.

- 32. : Two or more chemically bonded atoms.
- 33. : A fluid state of matter made of extremely high-temperatured ionized particles.
Down
- 1. Change : A change in matter that doesn't alter its chemical identity.
- 3. : A charged atom or group of atoms caused by a charge imbalance, which is produced by an unequal number of protons and electrons.
- 5. : A rigid state of matter in which the particles align in a fixed arrangement. A substance has an unchanging shape and volume.
- 6. : The change in state from a liquid to a solid caused by removing energy.
- 9. : The change in state from a gas to a liquid caused by removing energy.
- 10. Change : A change of one elemnt into another element by chahnges occuring in the nucleus of the atom.
- 11. law of thermodynamics : Scientific law that states that matter and energy cannot be created or destroyed, but can only transfer between objects or transform to a different form.
- 12. : The attractive force between any two objects based on their masses.
- 16. of Matter : The physical form of matter described by its physical characteristics.
- 17. : The change in state from a gas directly to a solid caused by removing energy.
- 18. : A pure substance formed by chemically compbining two or more elements.
- 21. : The measure of the amount of matter in an object.
- 22. : The amount of space that an object occupies.
- 24. Change : The change from one pure substance to another by the rearrangement of atoms in a chemical reaction.
- 26. : Anything that has mass and takes up space; a physical substance.
- 28. : The ability to do work.
- 29. : When a force acts on a moving object in the same or opposite direction of its motion or when energy is transferred from one object to another.
