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 entropy of the system, which is Î´Q/T, increases by Î´Q/273K. The heat Î´Q for this process is the energy required to change water from the solid state to the liquid state, and is called the enthalpy of fusion, i.e. Î´H for ice fusion.ntropy is a function of the state of a system, and has a value determined by the state variables of the system. The concept of entropy is central to the second law of thermodynamics.
