Explanation of how temperature affects the surface tension of water and why the temperature remains constant during boiling. Details the impact of hydrogen bonding on water's heating process.
As temperature increases, the surface tension of water decreases. This occurs because at higher temperatures, the kinetic energy of water molecules overcomes the cohesive forces of attraction between them, reducing surface tension.
When boiling water, the temperature remains constant at 100 degrees Celsius until all the water evaporates. This is due to the fact that the added heat energy is used to break intermolecular forces rather than increase the temperature.
Water has a high specific heat capacity due to strong hydrogen bonding. This explains why the metal pot heats up quickly compared to water when boiling, as water requires more energy to disrupt its hydrogen bonds before its temperature rises.
