The figure shown below is the heating curve obtained by heating 21.9 g of water from-10.0 to 140.0°C. The region labeled a represents the heating of ice to its melting point; the region b represents the metting of ice to form liquid water; region c represents the heating of water to its boiling point and region d represents boiling the water to convert it to a vapor Useful data is also displayed under the heating curve.
