Abstract: | This thesis discussed the general expression of the First Law of the thermodynamcs and its re-stricted expression under specified conditions, The transformation situations of energy in the irreversible pro- cesses was analysised emphatically in company with examples. The necessity introducing fundamental princi-ples of irreversible thermodynalics in the teaching of basic physics was point out last. |
