  • https://www.webstaurantstore.com/blog/postdetails.cfm?post=976 — a website article discussing the relationship between heat transfer and cooking, and the ways that the three methods of heat transfer (convection, conduction, and radiation) come into play when heating food. The article provides examples of each of these heat transfer methods, such as grilling for conduction, boiling for convection, and microwaving for radiation.
  • https://www.wonderopolis.org/wonder/why-cant-metal-objects-go-in-the-microwave — an article explaining why it’s unsafe to put metals objects, such as forks and cans, in microwaves. The article explains that during radiation heat transfer, metal objects don’t absorb the electromagnetic radiation, but rather reflect them since they conduct electricity, resulting in small bolts of electricity and potential fires within the microwave.
  • https://www.youtube.com/watch?v=IPDxtclZzVU — a video clip of the Myth Busters testing out the “Titanic Door” conundrum. In this clip, the two men attempt to both fit on top of a wooden door, but the buoyancy doesn’t allow them to do this while staying above water. As a solution, they place a life vest underneath the door, allowing them to lay on the door above water.
  • https://medium.com/the-physics-arxiv-blog/why-hot-water-freezes-faster-than-cold-physicists-solve-the-mpemba-effect-d8a2f611e853 — an article defining and explaining the Mpemba effect, in which warm water freezes faster than cold water. The article explains that many theories have attempted to provide explanation for the Mpemba effect, and that many still debate it today.
