Title: First Law of Thermodynamics
Summary: This video introduces the First Law of Thermodynamics (conservation of energy), explains the total energy of a system, including internal, kinetic, and potential energy, and describes how energy can be transferred through heat and work. It also discusses the distinction between closed and open systems and highlights the role of mass flow in energy transfer.
Learning Objectives: After watching this video, you will be able to explain the conservation of energy principle, identify components of total energy, and distinguish between energy transfer mechanisms for closed (control mass) and open (control volume) systems.

Title: Flow Work and Conservation of Energy for Open Systems
Summary: This video discusses the concept of flow work (flow energy) that leads to the enthalpy concept, introduces its role in the total energy of a flowing fluid, and demonstrates how it is incorporated into the first law of thermodynamics (conservation of energy) for open systems.
Learning Objectives: After watching this video, you will be able to define flow work, explain how it contributes to the total energy of a flowing fluid, and apply the first law of thermodynamics to open systems.
