  1. 1. The energy stored in the position or arrangement of particles in a substance, influencing changes in states of matter.
  2. 4. A state of matter consisting of charged particles, often found in stars and lightning.
  3. 7. The process of changing from a liquid to a gas state at the surface of a liquid, influenced by temperature and surface area.
  4. 9. The process of changing directly from a solid to a gas state without passing through the liquid state.
  5. 11. The energy of motion possessed by particles in a substance, increasing with temperature.
  6. 14. The temperature and pressure at which the distinction between liquid and gas phases of a substance disappears.
  7. 15. A state of matter with definite shape and volume, where particles are tightly packed and vibrate in fixed positions.
  8. 16. The process of changing from a gas to a liquid state by losing heat energy, often forming clouds or dew.
  9. 18. A graphical representation showing the states of matter of a substance under different conditions of temperature and pressure.

  1. 1. A transition between different states of matter, such as melting, freezing, vaporization, and condensation.
  2. 2. Energy transferred between objects due to temperature differences, causing changes in states of matter.
  3. 3. The process of changing from a liquid to a gas state, including both evaporation and boiling.
  4. 5. The process of changing directly from a gas to a solid state without passing through the liquid state, such as frost forming on a cold surface.
  5. 6. The process of changing from a liquid to a gas state throughout the liquid, requiring the addition of heat to reach the boiling point.
  6. 8. A measure of the average kinetic energy of particles in a substance, influencing the state of matter.
  7. 10. The process of changing from a solid to a liquid state by absorbing heat energy.
  8. 12. A state of matter with no definite shape or volume, where particles are far apart and move freely in all directions.
  9. 13. A state of matter with definite volume but no definite shape, where particles are close together but can move past each other.
  10. 17. The process of changing from a liquid to a solid state by losing heat energy.
  11. 19. A group of atoms bonded together, forming the basic structural unit of a substance.
