First and Second Laws of Thermodynamics

Words: 1198 Length: 3 Pages Document Type: Essay Paper #: 58255658

The first law of thermodynamics is mainly concerned with energy conservation and it states that energy cannot be created or destroyed. However, energy can be converted from one form to another. The total amount of energy entering into a system must be equal to the equal to the total amount of energy that is leaving the system (Toja-Silva & Rovira, 2014). Energy can be transformed and transferred but it must always remain constant.
The second law of thermodynamics is entropy. Entropy is the measure of change from order to disorder. Matter will move from an area of high concentration to an area of lower concentration. The law states that entropy of an isolated system that is not in thermal equilibrium will increase to a point of equilibrium (Toja-Silva & Rovira, 2014). It is not possible for heat to emanate from a cold object to a warm object without work. In…… [Read More]
