Final answer:
The correct option is Second Law.
The increase in entropy during the sublimation of dry ice is an example of the Second Law of Thermodynamics.
Step-by-step explanation:
The sublimation of dry ice, the solid form of carbon dioxide, serves as a compelling illustration of the Second Law of Thermodynamics. As dry ice undergoes sublimation, transitioning directly from a solid to a gas, the entropy of the system increases. This phenomenon aligns with the fundamental principle that governs thermodynamic processes – the total entropy of a closed system tends to increase over time.
The Second Law of Thermodynamics articulates that spontaneous processes are characterized by an increase in entropy. In the case of dry ice sublimation, the transition from a highly ordered solid state to a more disordered gaseous state exemplifies this principle. Entropy, often described as a measure of the disorder or randomness within a system, experiences a marked rise during this process. A gas, being inherently more disordered than a solid, reflects higher entropy due to the increased freedom of gas molecules to move randomly.
The sublimation of dry ice vividly demonstrates the natural tendency of systems to evolve towards states of greater disorder. This concept is integral to understanding the behavior of physical systems and underlies the spontaneous nature of processes that lead to an overall rise in entropy, as succinctly expressed in the Second Law of Thermodynamics.
