Water EquivalentMediumQuestion 30849

Question

Water equivalent of a calorimeter is the:
  1. A
    Mass of calorimeter
  2. B
    Volume of water equal to calorimeter's heat capacity
  3. C
    Mass of water having same heat capacity as calorimeter
    Correct
  4. D
    Thermal resistance

Correct answer

Mass of water having same heat capacity as calorimeter

Explanation

Water equivalent W = mc/c_water. It simplifies calorimetry calculations by treating the calorimeter as extra water.
