Potential energy

• What holds the molecules in a substance together?

  Intermolecular bonds
• What do intermolecular bonds prevent molecules from doing?

  Moving freely
• How can we visualize the intermolecular bonds in a substance?

  As springs holding balls of matter together
• What type of energy is stored in intermolecular bonds?

  Potential energy
• What type of energy do the molecules themselves possess?

  Kinetic energy
• How do intermolecular bonds affect the energy of molecules?

  They take some energy to prevent excessive movement
• What is the relationship between potential energy and intermolecular forces?

  Potential energy is related to intermolecular forces and bonds
• What happens to potential energy and intermolecular bonds as substances change states of matter?

  • In solids: Strong bonds, high potential energy
  • In liquids: Weaker bonds, moderate potential energy
  • In gases: Very weak bonds, low potential energy
• How are molecules arranged in a solid?

  Molecules are held in a rigid structure
• Why do solids have a rigid structure?

  Because the molecules are held together by very strong bonds
• What is the potential energy situation in solids?

  There is a large amount of potential energy stored in their bonds
• How do the bonds in liquids compare to those in solids?

  The bonds in liquids are weaker than those in solids
• What is the structure of a liquid?

  Molecules can move and flow around each other
• What is the potential energy situation in liquids?

  There is a moderate amount of potential energy stored in their bonds
• How do gas molecules behave compared to solid and liquid molecules?

  Gas molecules move freely and independently
• What is the potential energy situation in gases?

  There is a tiny amount of potential energy stored in their bonds
• Compare the potential energy in solids, liquids, and gases.

  • Solids: Most potential energy due to strong bonds
  • Liquids: Moderate potential energy due to weaker bonds
  • Gases: Least potential energy due to very weak bonds
