Answer:
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.
