    Water Equivalent of a Copper Calorimeter

    Definition: The water equivalent of a calorimeter is the mass of water that would absorb the same amount of heat as the calorimeter per degree Celsius rise in temperature.

    Formula: Water Equivalent (W) = (mass of calorimeter) x (specific heat of calorimeter) / (specific heat of water)

    Given:
    - Mass of copper calorimeter = 400 g
    - Specific heat of copper calorimeter = 0.1 cal/gC

    Solution:
    - Specific heat of water = 1 cal/gC (given)
    - Using the formula, W = (400 g) x (0.1 cal/gC) / (1 cal/gC)
    - W = 40 g

    Therefore, the water equivalent of the copper calorimeter is 40 g. This means that for every degree Celsius rise in temperature, the calorimeter would absorb the same amount of heat as 40 g of water would.
