Q2. Two identical 10 g iron springs, except that one has been wound using work W, are dropped into equal volumes of 15M HC1 in two identical constant volume calorimeters, that are adiabatically insulated. The HC1 will dissolve iron springs. What difference can be observed in the two calorimeters after the springs were totally dissolved?
