Energy transfer and transformations can increase the disorder of a system from "summary" of Physics 11 by British Columbia. Schools Department. Curriculum Development Branch
When energy is transferred or transformed within a system, there is a tendency for the system to become more disordered. This increase in disorder is a result of the nature of energy transformations and the laws of thermodynamics. Energy can be transferred in various ways, such as through heat, work, or radiation. During these transfers, some energy is always lost to the surroundings in the form of heat. This loss of energy contributes to an increase in disorder within the system. The concept of disorder in a system is often referred to as entropy. Entropy is a measure of the randomness or disorder within a system. As energy is transferred or transformed, the entropy of the system tends to increase. This is known as the second law of thermodynamics, which states that the total entropy of an isolated system always increases over time. One way to understand this concept is through the example of a hot cup of coffee left on a table. As the coffee cools down, energy is transferred from the coffee to the surrounding air, increasing the disorder of the system. The molecules in the coffee slow down, and the temperature of the coffee becomes more uniform with its surroundings, leading to an increase in entropy. In summary, energy transfer and transformations can lead to an increase in the disorder of a system due to the nature of energy transfers and the laws of thermodynamics. This increase in disorder, or entropy, is a fundamental concept in understanding the behavior of systems as they interact with their surroundings.
