What is entropy?
Entropy describes the tendency that the systems move from a higher organization to the lowest organization at the molecular level. In your daily life, you intuitively understand how entropy works whenever you pour sugar into your coffee or melt the ice cube into a glass. Entropy can affect the space into which the substance spreads, its phase changes from the solid to the liquid to the gas or its position. In physics, entropy is a mathematical measurement of change from greater to less potential energy related to the second law of thermodynamics.
entropy comes from the Greek word, "transformation". This definition gives us insight into the reason why things seem to change. Systems can only maintain an organization at a molecular level if energy is added. For example, the water will only boil until you hold the pan above the flames. You add heat, a form of kinetic energy to speed up the molecules in the water. If the heat source is removed, we can all appreciate the water gradually cooled toroom temperature. This is due to entropy because water molecules tend to use their accumulated potential energy, release heat and end with lower potential energy.
The temperature is not the only transformation connected to entropy. Changes always include transition from imbalances to balance, which is in line with the transition to reducing the order. For example, the molecules have always spread to uniformly fill the container. When we bandage the food dye in a clear glass of water, even if we do not mix it, this unified concentration of drop gradually extends until each part of the water has the same color density.
Another type of entropy, which has to do with visible movement (unlike invisible heat movement), involves gravity. If we put energy into the system, such as the arm and the ball, we raise the object, the totard of the earth falls. The increased position has higher potential energy. When the object falls,It is converted into kinetic energy of movement. The object always ends with the position of the lowest possible energy, such as resting on the floor.
6 Entropy evaluates the amount of failure, understood as a change in heat, from an earlier point to a later point. This must happen in a "closed" system where no energy does or out. Theoretically, it can be measured, but it is practically very difficult to create an absolutely closed scenario. In the above example of food coloring, some of the food color may be evaporation, a separate process from the uniform distribution of Solut.
