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.
Entropy of Phase Changes. Sometimes calculating entropy changes using equation (1) is not so complicated. If the temperature stays constant as heat is added or removed, equation (1) is easy to use.During phase changes, as discussed in Enthalpy 4 and 5, the temperature stays constant while the substance accepts or gives up heat, until the phase change is complete.Thus, equation (1) can be applied directly. Predict the entropy change when 100.0 g of liquid benzene (C.ntropy of Phase Changes. Sometimes calculating entropy changes using equation (1) is not so complicated.
