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.
1 Î´ (delta) means change in. 2  Î´H is the change in enthalpy or heat equivalent. 3  T is the thermodynamic temperature, the temperature in Kelvin. 4  Î´S is the change in entropy or dispersion of energy, where gases are more dispersed and have greater entropy than liquids, etc.
