  1. 2. a fluid state of matter made of extremely high temperature ionized particles
  2. 6. temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid
  3. 9. A charged atom or group of atoms caused by a chargeimbalance, which is produced by an unequal number of protons and electrons.
  4. 10. A pure substance made of only one kind of atom.
  5. 13. The attractive force between any two objects based on their masses. The strength of gravity decreases rapidly as the two objects move apart.
  6. 14. speaking of something that contains only one kind of matter
  7. 15. change of a solid into a liquid when heat is applied
  8. 16. The ability to do work. Energy exists in many forms and can transfer between objects or change formfirstlawofthermodynamice Scientific law that states that matter and energy cannot be created or destroyed, but can only transfer between objects or transform toa different form. Also called the law of conservation of matter and energy.
  9. 21. One of the four principal conditions in which matter exists-solid, liquid, gas, and plasma
  10. 23. the process of changing from a solid to a gas without passing through an intermediate liquid phase
  11. 24. A charged atom or group of atoms caused by a chargeimbalance, which is produced by an unequal number of protons and electrons.
  12. 25. a fluid state of matter
  13. 26. process that causes a substance to change from a liquid to a solid
  14. 27. the process by which water vapor in the air is changed into liquid water
  15. 28. the measure of hotness or coldness expressed in terms of any of several scales
Down
  1. 1. The measure of the amount of matter in an object
  2. 2. A change in matter that doesn't alter its chemical identity. Physical changes include changes of state, changing shape, polishing, dissolving, etc.
  3. 3. The amount of space that an object occupies
  4. 4. The force of gravitational attraction between an object's mass and its resident planet.
  5. 5. material substance that constitutes the observable universe
  6. 7. a state of matter that has no fixed shape and no fixed volume
  7. 8. Work is done 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.
  8. 11. the process by which a liquid turns into a gas
  9. 12. the conversion of a solid or a liquid into a gas
  10. 15. Two or more chemically bonded atoms. Molecules can be made of just one kind of element or a combination of elements
  11. 17. the laying down of sediment carried by wind, flowing water, the sea or ice
  12. 18. A pure substance formed by chemically combining two or more elements.
  13. 19. a material made up of two or more different substances
  14. 20. The change from one pure substance to another by the rearrangement of atoms in a chemical reaction. We typically recognize chemical changes by a change in color, change in energy, formation of a gas, and/or formation of a solid.
  15. 22. one of the three main states of matter
