anthropy definition
Entropy Definition. Entropy is defined as the quantitative measure of disorder or randomness in a system. The concept comes out of thermodynamics, which deals with the transfer of heat energy within a system. A facet joint has two bony surfaces with cartilage between them and a capsule of ligaments surrounding it. 1  Synovial fluid lubricates the joints, as is the case with other joints (e.g., the knee). Facet joints help keep the normal alignment of the vertebrae and limit motion. Thermodynamics. ( 1 on a macroscopic scale) a function of thermodynamic variables, as temperature, pressure, or composition, that is a measure of the energy that is not available for work during a thermodynamic process. A closed system evolves toward a state of maximum entropy. The facet joints and intervertebral disc form a three-joint complex between adjacent vertebrae. A facet joint has two bony surfaces with cartilage between them and a capsule of ligaments surrounding it. Synovial fluid lubricates the joints, as is the case with other joints (e.g., the knee). 1. a function of thermodynamic variables, as temperature or pressure, that is a measure of the energy that is not available for work in a thermodynamic process. Symbol: S. 2. (in data transmission and information theory) a measure of the loss of information in a transmitted signal. Calculating Entropy. In an isothermal process, the change in entropy (delta-S) is the change in heat (Q) divided by the absolute temperature (T): delta-S = Q/T. In any reversible thermodynamic process, it can be represented in calculus as the integral from a process's initial state to its final state of dQ/T. In a more general sense, entropy is a measure of probability and the molecular disorder of a macroscopic system. A facet joint has two bony surfaces with cartilage between them and a capsule of ligaments surrounding it. 1  Synovial fluid lubricates the joints, as is the case with other joints (e.g., the knee). 2  The primary cause of facet arthropathy is spinal degeneration which typically occurs in later life. 1. a function of thermodynamic variables, as temperature or pressure, that is a measure of the energy that is not available for work in a thermodynamic process. 2. (in data transmission and information theory) a measure of the loss of information in a transmitted signal. (on a macroscopic scale) a function of thermodynamic variables, as temperature, pressure, or composition, that is a measure of the energy that is not available for work during a thermodynamic process. A closed system evolves toward a state of maximum entropy. 1. Symbol S For a closed thermodynamic system, a quantitative measure of the amount of thermal energy not available to do work. 2. A measure of the disorder or randomness in a closed system. 3. A measure of the loss of information in a transmitted message.
