Thermodynamics dictates that a system contains internal energy, kinetic energy, and potential energy. However, a system never contains heat or work. ; they only exist when crossing the system boundary during a change of state (a process). Path Functions: Both heat ( ) and work (
Most engineering texts adopt the :
Heat is energy transferred solely due to a between a system and its surroundings. Unlike work, heat is a "low-grade" energy form, often resulting in disorganized molecular motion. Mechanisms of Heat Transfer engineering thermodynamics work and heat transfer
