Analysis of Thermodynamic and Statistics for Irreversibility of Free Expansion and Diffusion Process
Ying Lü · Luoyang Shifan Xueyuan xuebao · 2008
The expansion of freedom and diffusion process was analyzed respectively with thermodynamics and statistics.From the view of thermodynamics,free expansion is irreversible in mechanical factors in the irreversible process,than diffusion process is irreversible in chemical factors in the irreversible process.From a statistical perspective,they are all changes from the small probability thermodynamic state to that of high probability.Diffusion process can be regarded as the superposition of two free expansion processes.
