1. How Microwave oven works

   • Magnetron- produces short microwaves
   • Wave Guide- rectangular metal tube
   • Stirrer- Fan like device that spreads wave throughout the oven
   • Water molecules in food- start heating up and give off friction to heat the food
   • Water molecules in food have a positive and negative end
   • Waves from the fan bounce off the walls until they enter the food
   • Microwave is smaller and traps the heat easily
   • A microwave cooks things a lot faster than an oven
   • Fan is located on top while in oven its in the back middlel
   • About 2 1/2 billion times a second the molecules then heat up while in a microave

4. How ovens work

   • Thermal oven- heating elements on top and bottom of oven
   • Oven fan- collects oven heat and sucks it in then lets out the hot air back into the oven
   • Food done in thermal oven is done about 25% faster
   • Foods cook more evenly
   • Everything will be done at around the same time
   • Convection oven has a fan to distrubite air evenly throughout oven
   • When cooking with convection oven cook about 25 degrees lower than intended
   • Use a shallow pan when cooking something in convection oven
   • Use light pans or bright pans
   • Cooking a turkey can be done an hour quicker in a thermal oven
   • Heat circulates in the oven to heat everything
   • There are no hot or cold spots in the oven
   • The heating elements gradually radiates heat to food
