# ENGR 2070 - Thermodynamics

Credits: 3
Hours/Week: Lecture None Lab None
Course Description: This course covers thermodynamics systems and their equilibrium. Topics include work, heat and the first law of thermodynamics; the properties of pure substances and their equation of state; ideal and real gases and gaseous mixtures. Entropy, reversibility and the second law of thermodynamics are presented. The Carnot cycle is covered along with other engineering cycles, process equations and their efficiencies.
