A calorimeter contains ice. Determine the heat capacitiy of the calorimeter if `2.1kJ` of heat is required to heat it togheter with its contents from `270^(@)K` to `270^(@)K`, and `69.72kJ` of heat of required to raise its temperature of `272K` to `274^(@)K`.
(`L` of ice `=336xx10^(3)Jkg^(-1)`, specific heat capacity of ice `=2100kg^(-1)K^(-1)`)
