=======Reviewing Thermal Phenomena=======
Review of the thermal phenomena:\\
  * Objects left for a long time in a room reach the same temperature (room temperature)\\
  * Materials conduct heat energy at different rates\\
  * Styrofoam conducts heat slowly and is an insulator\\
  * Metals conduct heat quickly; metals are conductors\\
  * Conductivity: property of a material that refers to how quickly it conducts heat energy\\
  * Conductivity is different from density; conductivity refers to how fast energy flows through a material. Density refers to how much "stuff" there is in a given volume.\\
  * Hot and cold water reach equilibrium when mixed together. \\
