WebTable 11.3 Latent Heats of Fusion and Vaporization, along with Melting and Boiling Points. Let’s consider the example of adding heat to ice to examine its transitions through all three phases—solid to liquid to gas. A phase diagram indicating the temperature changes of water as energy is added is shown in Figure 11.10. WebSep 28, 2024 · This process is known as boiling. While boiling water is a physical change, it can also be used to produce chemical changes. For example, when water boils, it can break apart food molecules, making them easier to digest. In addition, boiling water can kill bacteria and other microorganisms that may be present in the water.

Boiling occurs when the vapor pressure of the hot liquid equals the atmospheric pressure of its surroundings. When you reduce the pressure of its surroundings, it takes less vapor pressure to equal that, which occurs at a lower temperature. This is why reducing the ambient pressure reduces the boiling point …
