Control mass thermodynamics is a branch of thermodynamics that deals with the study of energy and its transformations within a fixed or closed system, where there is no mass exchange between the system and its surroundings.
The laws of control mass thermodynamics are the first and second laws of thermodynamics. The first law states that energy cannot be created or destroyed, only transferred or converted from one form to another. The second law states that the total entropy of a closed system will always increase over time.
Control mass thermodynamics is applied in various fields such as engineering, chemistry, and physics to analyze and predict the behavior of energy in different systems. It is used to design and improve energy-efficient processes and systems, such as power plants and engines, and also to understand natural phenomena like weather patterns and ocean currents.
The key concepts in control mass thermodynamics include energy, work, heat, entropy, and internal energy. Energy is the ability to do work, and it can exist in different forms such as mechanical, thermal, and chemical. Work is the transfer of energy through a force acting over a distance, while heat is the transfer of thermal energy between two objects at different temperatures. Entropy is a measure of the disorder or randomness in a system, and internal energy is the total energy of a system.
The main difference between control mass thermodynamics and control volume thermodynamics is that control mass deals with a fixed amount of mass within a closed system, while control volume deals with a specific region or volume within a system where mass and energy can flow in and out. Control volume thermodynamics is often used to analyze the performance of devices such as turbines and compressors, while control mass thermodynamics is used for systems with no mass exchange, like a sealed container.
