It is often caused by gallstones. Common symptoms are severe pain in the upper abdomen, nausea, and vomiting. Treatment is usually a few days in the hospital for intravenous (IV) fluids, antibiotics, and medicines to relieve pain. Chronic pancreatitis does not heal or improve.
Definition of Entropy. Entropy is a thermodynamic measure of the disorder in a system. The entropy of a reaction is calculated by comparing the disorder of the products and reactants. An increase in entropy corresponds to an increase in disorder and a dispersion of energy. An important example of a system with increasing entropy is water boiling to make steam, where the molecules have much more freedom and are more disordered.
The second law of thermodynamics gives a precise definition of a property called entropy. Entropy can be thought of as a measure of how close a system is to equilibrium; it can also be thought of as a measure of the disorder in the system. The law states that the entropyâthat is, the disorderâof an isolated system can never decrease.
