Thermochemistry energy and heat

This lesson is intended to increase students' understanding of heat and chemical reactions. Thermochemistry part of thermodynamics (study of heat) the study of energy transfer during reactions defined through Òsystem Ó and Òsurroundings. Chemical thermodynamics thermodynamics is defined as the branch of science that deals with the relationship between heat and other forms of energy, such as work. • thermochemistry is the study of the heat flow that accompanies chemical reactions • heat energy may be used not only to change the temperature of. Thermochemistry is a sub-branch of thermodynamics, the study of energy transfer it developed from the study of heat engines (specifically steam engines), in the 18th.
