While Thermodynamics and Heat Transfer are closely related fields in thermal engineering, they focus on different aspects of energy. 🔥 Thermodynamics: Deals with energy, heat, and work and how they relate to system properties (pressure, volume, temperature). Focuses on the amount of energy transferred and the state change of the system. Does not consider how fast the energy transfer occurs or by what physical mechanism. 🌡️ Heat Transfer: Focuses on how energy moves due to temperature differences. Describes the rate of energy transfer and mechanisms involved. Essential for the design of thermal systems like heat exchangers, radiators, and insulation.
