American Intercontinental University Unit3 Individual Project The Laws of Thermodynamics May 17, 2015 Abstract Energy is the driving force for the universe. There are so many different forms of energy. The laws of thermodynamics govern how and why energy is transferred. Before the different types of energy resources and their uses are discussed, it is important to understand a little about the basic laws of energy. (Environmental Science 2013) The Laws of Thermodynamics The laws of thermodynamics describe how temperature, energy, and entropy behave under certain circumstances. A thermodynamic system is one that interacts and exchanges energy with the area around it. The exchange and transfer need to happen in at least two ways. At least one way must be the transfer of heat. If the thermodynamic system is "in equilibrium," it can't change its state or status without interacting with its environment. In the laws of thermodynamics you're in equilibrium, you're a "happy system," just minding your own business. You can't really do anything. If you do, you have to interact with the world around you. ( nd) Introduction In the laws of thermodynamics it states that when heat is added to a system, someenergy stays in the system and some leaves the system. The energy that does stay creates and increases the internal energy in the system.( nd) Through the sun, it creates heat, which starts the Photosynthesis process which is is a process used by plants and other organisms to convert light energy, from the sun, into chemical energy that can be later released to fuel the organisms' activities.( nd) When we look at the second law of thermodynamics explains that it is impossible to have a cyclic (repeating) process that converts heat completely into work. It is also impossible to have a process that
