Below are the four links that relate to Unit 4 of our class (Phase Changes, Heat Transfer):
-
Food Science Basics: Heat Transfer:
- Cooking is simply the act of applying heat to foods to prepare them for eating. This article explains four different ways of cooking that all create heat transfer. They include conduction, convection, radiation, and induction cooking. Conduction is the direct transfer of heat between adjacent molecules. Convection is the transfer of heat through gases or liquids. Radiation is the transfer of energy through waves of electromagnetic energy through space. Lastly, induction cooking is a relatively new cooking method that transfers heat through a specially designed cook top made of smooth ceramic material over an induction coil. This article aligns well with with the things we have learned in Unit 4.
- How Do Microwave Ovens Work?
- Microwaves are convenient, ubiquitous, and easy to use. This is a great educational video that answers the following question: how do microwave ovens work? Furthermore, what do people mean when they say a microwave cooks food inside out? This video does an excellent job of answering those questions in a fun way. Enjoy!
- From Bombs to Bananas: A Dose of Radiation Reality
- Radiation may be frightening, but we live with a surprising amount of natural radiation every day. Radiation is tasteless, odorless, and, except in the greatest intensities, invisible. This is a very interesting article that talks expains the following things: provides a definition of radiation, talks about the different types of radiation, explains where radiation comes from, explains why radiation is dangerous, and talks about the common items that radiation is found in (such as food and other sources). Phenomenal article!
- How Does Insulation Work?
- This is another great article that I learned a lot from. It provides quality information about one of the subjects that we learned about in Unit 4: insulation. Similar to the article above, this is loaded with the following information: how insulation works, r-values, types of insulation, and insulation materials. I highly recommend taking a glace!
Thanks for checking out my Unit 4 links!
