Sketch a heating curve for water at 101kPa using the information from the phase diagram. Label the melting point and
boiling point temperatures on your heating curve

Please find attached a sketch of the heating curve of water at atmospheric pressure ( approximately 101 kPa) as traced from an online source

Explanation:

Given that the pressure at 101 kPa is approximately 1 atmosphere, we have;

The melting point and the boiling point occurs at approximately 0°C and approximately 100°C, respectively;

The melting point and the boiling point experience latent heat, therefore that temperature remains the same, though heat is continuously added

Also, given that the latent heat of vaporization (22.6 × 10⁵ J/kg) is approximately 7 times the latent heat of fusion is (3.33 × 10⁵ J/kg), the length of the plateau representing evaporation would be approximately 7 times longer than the length representing fusion.

The heating curve obtained from an online source for water at atmospheric pressure, is presented in the attached sketch.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
