The amount of heat required to change a liquid into a solid is known as what?

The term "Latent Heat of Fusion" specifically refers to the amount of heat energy that is absorbed or released when a substance changes its state from solid to liquid or vice versa, without a change in temperature. In the context of the question, when a liquid transforms into a solid, it releases heat, which is categorized under latent heat.

To further clarify, during the freezing process, molecules lose energy and transition from a less organized liquid state to a more structured solid state. The energy released during this process is what we refer to as the latent heat of fusion. This is crucial in refrigeration and phase change processes, as it directly impacts the efficiency and functionality of various systems.

The other terms mentioned do not apply to this scenario: "Latent Heat of Frozen State" is not a standard term used in thermodynamics, while "Specific Heat of Fusion" is incorrect because specific heat refers to the amount of heat required to change the temperature of a unit mass of a substance by one degree, not a state change. "Sensible Heat" is the heat associated with temperature changes in a substance, not changes in phase, and is relevant when discussing heat energy that contributes to temperature variations rather than phase transitions.
