Summary:

• Temperature of an object depends on the average amount of energy per molecule.
• Materials with a high specific heat capacity, such as water, need a lot of energy to raise their temperature.
• Materials with a low specific heat capacity, like sand, glass, and metals, don’t require much energy to raise their temperature.

Optional: Watch the MythBusters demonstrate the high heat capacity of water by dipping their fingers into molten lead. They can do this without getting burned because their hands are wet.
