Answer

Brief Explanations:

Intermolecular forces are forces of attraction between substances due to the distribution of electrons. Chemical changes result in new substances, while physical changes do not. Scrambling eggs is a chemical change as proteins denature. Silver spoon tarnishing is a chemical change as silver reacts with sulfur - containing compounds. A puddle drying up is a physical change as water changes from liquid to gas without forming a new substance. Chopping onions is a physical change as it only changes the physical form of the onion.

Answer:

  1. B. A force of attraction between substances due to distribution of electrons
  2. Scrambling eggs in a bowl: Chemical Change
  3. A silver spoon tarnishing: Chemical Change
  4. A puddle drying up: Physical Change
  5. Chopping onions: Physical Change
