Energy Unit 4 #4

These two beakers contain the same liquid substance at the same temperature. How does the thermal energy of the liquid in the larger beaker compare to the thermal energy of the liquid in the smaller beaker?

• The liquid in the
  larger beaker has
  less thermal energy
  than the liquid in
  the small beaker.
• The exact volume of
  liquid in each beaker
  must be know to
  compare the thermal
  energy of the liquids
• The liquid in the
  larger beaker has
  the same amount of
  thermal energy
• The liquid in the
  larger beaker has
  more thermal energy
