Document Summary

Can be transformed from one form to another. Inversely related with potential energy (eg. ball falling down energy) Energy which an object has bc of its position. Potential to be converted into other forms of energy. Energy may be converted from one form to another, total quantity remains constant. Eg. eating- chemical bonds broken to get energy to eat. Substance or mixture of substances singled out for study which a change occurs. Work (w) - energy transfer into/out if thermodynamic system. Energy transfer into/out of thermodynamic system results from temperature difference b/w system and its surroundings. Flows increase temp to decrease temp (hot to cold) Heat flows into system appearing in it as an increasing internal energy of system. Change in internal energy of a system, u equals heat + work. Heat absorbed or evolved from a rxn system to retain fixed temperature of the system under conditions specified for the rxn.
