  1. 4. Explanation of how the particles in gasses behave. States that all matter is made of tiny particles, these particles are in a constant and random motion, that the particles collide and that the energy particles lose when they collide is negligible.
  2. 7. when a liquid's temperature is lowered, making the average kinetic energy of the molecules decrease. When enough of this energy is removed, the molecules become fixed into a definite shape or position.
  3. 9. Anything that takes up space and has mass
  4. 10. The process of a gas turning directly into a solid without passing through the liquid state.
  5. 11. Occurs at the surface of a liquid and can happen at almost any temperature. Particles must have enough kinetic energy to escape the attractive forces of the liquid.
  6. 13. Happens when the temperature reaches a certain level and the solid turns into a liquid. Energy is needed for the order of the solid to change. The heat of fusion is the energy required for the solid to turn into a liquid at its melting point.
  7. 14. The temperature at which the pressure of the vapor in the liquid is the same as the external pressure acting on the surface of the liquid.
  8. 15. The energy required to change a substance from solid to liquid at its melting point.
  9. 17. It has a definite shape and volume. The particles that make up the state are closely packed together. They form into a physical shape because they have so little kinetic energy that the particles can not overcome their attraction to each other.

  1. 1. Its particles are constantly moving, but not as quickly as the gas particles. It has less energy than gas.They don’t overcome their attractions. They do take the form of their container, but stick together, giving it a volume.
  2. 2. The process where a gas transforms into a liquid. This is a reverse of vaporization
  3. 3. This happens when particles move fast enough to escape the forces that attract them to other particles, entering the gas state. There are two ways this can occur: evaporation and boiling.
  4. 5. The amount of energy required for the liquid at its boiling point to become a gas.
  5. 6. Way of how liquid can vaporize. This occurs when a liquid is at a specific temperature.
  6. 8. Particles are in constant motion, colliding with each other and with the walls of their container. They don't don’t have a fixed volume or shape. The particles spread out in their container.
  7. 12. The temperature where a solid becomes a liquid.
  8. 16. The process of a solid changing directly to a gas without forming a liquid.
