Thermodynamics

Introduction Thermodynamics, as with most concepts in science and physics, is most accurately described using mathematical equations. However, simple explanations, although not perfectly accurate, are sufficient to convey the information needed to understand everyday experiences. This paper is an attempt to simplify these concepts. Thermodynamics simply describes the movement of heat. Thermodynamics is derived from thermo, meaning heat, and dynamics, (literally “power”), […]

This simple system shows the application of the Second Law. The compressor A adds energy to the refrigerant, and it becomes hot, just the way a hand operated tire pump does. Since the compressed refrigerant is hotter than the air blowing across the condenser B , the heat will flow to the cooler air. This is a transfer of heat
