Compare and discuss the first and second laws of thermodynamics
What will be an ideal response?
The first law of thermodynamics states that energy can change from one form to another but cannot be created or destroyed. That is, the total energy in the universe remains constant. However, the second law states that the entropy of energy in the universe will change from a more ordered state to a less ordered state. Entropy in the universe is increasing as energy is converted from high quality (capable of doing work) to low quality (dispersed and unavailable for doing work). Low-quality energy from organisms is usually released into the environment as heat. For example, if you were to eat a bowl of oatmeal for breakfast, your digestive system would digest the starch to glucose, and your cells would then burn the glucose to convert the stored energy to ATP for cellular work, but much of the energy is lost as heat during these transformations. The products of this process are carbon dioxide and water, neither of which has any potential energy for you to use. Therefore, you have to keep taking in more chemical energy in food to keep your system running.
