One of the common phrases used to describe entropy is “Time’s arrow”. This is because nature tends from order to disorder in isolated systems. Take for example, your earbuds. Out of your …show more content…
Heat change and enthalpy can be used reciprocally, but only if the reaction occurs at constant pressure. The change in enthalpy is equivalent to the heat change, which is absorbed or released. Enthalpy can be influenced by the amount of materials used and the state of those materials. In either exothermic or endothermic reactions, enthalpy can be written two ways. In exothermic reactions enthalpy is written as negative, because energy is released. In endothermic reactions, enthalpy is written as positive because energy is absorbed. Take a refrigerator, for example. Refrigerants such as freon are evaporated by refrigerators, providing the perfect example of enthalpy of vaporization (liquid to gas), which is equal to how refrigerated the food is. Another example is a heat packet. The chemicals of the packet heat up when they are exposed to oxygen, so when the packet is crushed it heats up, supplying another great example of …show more content…
Meaning that under the correct conditions, matter can acquire the traits needed for life. England’s theory is not meant to replace Darwin’s theory of evolution, but rather to underlie it. His idea relies on the second law of thermodynamics, or the law of increasing entropy, also known as the “arrow of time”. Energy disperses over time. Ultimately, the system will arrive at a phase of maximum entropy called the “thermodynamic equilibrium,” in which all energy is distributed evenly. Entropy describes nature’s tendency from order to disorder in closed systems, but in open systems, the entropy is low. This phenomenon happens because the open system divides energy unevenly among its atoms by greatly expanding the entropy of its environment. Reproduction is one of the processes in which a system may dissipate a growing amount of energy over time. According to
