Rest Meat Before Cutting and Serving. Doneness temperatures reflect ideal serving temperatures after resting. Meats may need to be removed from heat about 5Â°F lower than the recommended doneness temperature to prevent overheating. Resting meat prior to serving is recommended for best quality. Warning: Serving meat at temperatures below USDA minimum safety recommendations should be done at your own risk. See recommended Min. Safe Temperature
Thermionic emission is the thermally induced flow of charge carriers from a surface or over a potential-energy barrier. This occurs because the thermal energy given to the carrier overcomes the work function of the material.
