Everyday Applications

       Think about when you cook an egg, for those of you who do not cook, just pretend. When you take an egg out of the refrigerator it is at a temperature of about 5^oC . If you place it in a pot of boiling water, heat is transferred from the egg’s surface to its center. The temperature throughout the egg is changing with time, eventually cooking the egg.

    You just washed your hair and you need it dry really fast what do you do? You blow dry it. When blow drying your hair, heat is transferred from the blow dryer to the hair strands, heating up the hair strands over time until they dry.
