A quantity of frozen water (also called ice) of mass 0.0320 kg is initially at a temperature of -3.00° C. It undergoes a series of physical changes at atmospheric pressure. The specific heat of ice is 2090 J/kg.°C. The specific heat of water is 4186 J/kg-°C. The specific heat of steam is 2010 J/kg.°C. The heat of fusion of water is 3.33 x 105 J/kg. The heat of vaporization of water is 2.26 x 106 J/kg. (a) Calculate the amount of heat transfer required to raise the temperature of the sample to its freezing point. J (b) Once the ice reaches the freezing point additional heat transfer is supplied and the ice melts. Calculate the amount of heat transfer required for this process. (c) The melted ice (now liquid water) is heated to its boiling point. Calculate the amount of heat transfer required for this process. J (d) The water that has reached its boiling point is heated and completely vaporized. Calculate the amount of heat transfer required. J J (e) The vaporized water (steam) is heated to 118° C. Calculate the amount of heat transfer required. J (f) During which (one or more) of these processes does the temperature of the sample remain essentially constant? Onone of them Oa nb с nd ne
