An iron ball of mass 500 gram at a temperature of 500 °C is cooled by placing it on a block of ice taken from the freezer. If the mass of the ice is 800 gram and its initial temperature is -10 °C, then determine what is the final configuration? That is, is the final state of the H2O all ice, ice-water mixture, water only, water- steam mixture, or steam only? If it is a mixture, compute the proportions. Evaluate the final temperature. The specific heat of iron is 0.107 cal/g•°C.
Hint: compute the energy required for the H2O to bring it to each end of a phase transition, and Determine the energy available from the iron for each of these points.
