(6) A 470-g ofan unknown metal was heated to 100.0°C and the hot metal was immediately added into 30.0 g of cold water in a Styrofoam calorimeter. The initial temperature of cold water and calorimeter was 22.0 â After metal, water and calorimeter have come to thermal equilibrium, their final temperature was 32.2â (a) Calculate the amount of heat (in Joules) absorbed by water? (b) Calculate the amount of heat absorbed by calorimeter, which has heat capacity of 25 J/°C (c) What is the total amount of heat lost by hot metal? (d) Calculate the specific heat of metal
