First Law of Thermodynamics Energy can not be created or destroyed, but changed from one form to another Applied to system and surroundings System - part in which the process occurs - boundaries can be real or imaginary, rigid or flexible Surroundings - everything not included in the system (Energy of the system) + (Energy of surroundings) = 0

Closed System Energy Balance No transfer of mass to surroundings (Energy of surroundings) = Q W Energy can only be transferred by heat or work Sign depends on which direction the heat and work move (Energy of system) = U t = U + E K + E P Combining equations U + E K + E P = Q W

Closed System Energy Balance Q is positive when transferred to the system from the surroundings W is positive when transferred to the system from the surroundings U + E K + E P = Q + W U E K E P +Q +W
