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.
