Document Summary

Enthalpy (h) is a measure of the amount of heat energy contained in a substance. This is released as delta sign h (the change in enthalpy in the course of a reaction. Heat is transferred from a system to its surroundings or vice versa. Heat transferred to surroundings denotes an exothermic reaction (delta h is negative) and the reverse denotes an endothermic reaction (delta h is positive). Systems: open (matter and energy transferred), closed (only energy transferred), isolated (neither transferred) Q = mc (delta t) meausres the heat gained or lost by water or other calorimetric liquid or substance heating or cooling.
