First law of thermodynamics
Energy cannot be created or destroyed.
Second law of thermodynamics
Energy has quality as well as quantity. Processes occur in the direction of decreasing energy.
Closed system
A system in which no matter is allowed to enter or leave. Matter is fixed.
Isolated system
A system that can exchange neither energy nor matter with its surroundings.
Open system
A system in which exchanges of matter or energy occur across system boundaries.

e = E/m (kJ/kg)
e = The total energy of a system on the unit mass basis (pg. 9)
Macroscopic energy
A form of energy a system possesses with respect to an outside reference frame (KE or PE).
Microscopic energy
A form of energy related to molecular structure or the degree of molecular activity. The sum of microscopic forms of
energy is the internal energy, denoted by U.
KE = (m*V^2)/2 (kJ)
The energy system possesses as a result of its motion relative to some reference frame (pg. 10)
ke = (V^2)/2 (kJ/kg)
per unit mass basis of KE (pg. 10).
