Peter has an earthen oven that is heated by setting a fire inside of it. After the fire is cleaned out, the oven’s insulated structure retains thermal energy and is able to bake foods. Unfortunately, Peter has been burning many loaves of bread in this oven, but has noted his observations as shown in the table. Use what you learned about thermal energy transfer and specific heat to describe three possible solutions to help Peter from burning his bread.
