Grade 6 Heat Transfer

The metal lid is stuck on a glass jar of jelly. Why does running hot water over the lid help you get the lid off?
  1. Thermal expansion causes the lid to expand making it easier to remove.
  2. The heat chemically changes the glue around the edge releasing the lid from the jar.
  3. The heat warms the jelly causing it to push the lid off the jar.
  4. None of the above.
