1) An aluminum calorimeter of
mass 58 g, has 155 g water, both at a temperature of 21°C. A 108-g
piece of metal originally kept in boiling water (T = 100°C) is
transferred to the calorimeter. The final equilibrium temperature
of the mixture is 26.6°C. Calculate the specific heat of the metal
(in J/kg). Specific Heats: Al = 900 J/kg, water =4186 J/g
2) How much heat, in kilo-joules, is required to convert 19 g of
ice at -13°C into...
