Interesting Facts:
When two materials at different temperatures are placed in contact with each other, heat passes from the hotter object to the colder one until their temperatures are the same. This heat transfer is known as conduction. How quickly heat is transferred between the two materials depends on several variables. The more surface contact between the materials, the faster the transfer. Different materials also ‘heat up’ at different speeds. When heat travels easily through a material it is known as a heat conductor, and when heat travels slowly the material is known as a heat insulator.
A metal spoon at room temperature is the same temperature as the air. It might feel colder than a wooden or plastic spoon because metal conducts heat so much better. Because your hand is hotter than room temperature, heat is conducted away from it, and a metal spoon cools your hand faster. Heat flow depends strongly on the geometry and type of materials. For example, the recently discovered thinnest material graphene, which is composed of just a single layer of carbon atoms, is known for its fast heat transfer properties. |
