In this video, you will learn about the Zeroth and First Laws of Thermodynamics, a topic in Engineering Sciences, FE Industrial, and Systems.
The Zeroth Law of Thermodynamics states that when two bodies are in thermal equilibrium with a third body, they are in thermal equilibrium with each other, and therefore, they are at the same temperature.
The First Law of Thermodynamics states that energy can neither be created nor destroyed but can be converted from one form to another. The First Law of Thermodynamics defines the conservation of energy.
Furthermore, the tutor explains Heat, Work, and sign conventions with the thermodynamic idea of a steam cycle that generates power.
• Heat (Q) is energy transferred into a system due to a temperature difference.
• Work (W) is energy transferred out of a system mechanically.
Note: The temperature we put in (boiler) creates work coming out (turbine). The sign convention is reversed for reversed cycles in HVAC.
