REMARKS ON HEAT AND WORK TRANSFERS IN SYSTEMS WITH UNIFORM INTENSIVE PROPERTIES

The differential forms of heat and work, owing to their dependence upo n parameters characterizing the interaction between system and environ ment (and not only upon the state functions of the system), differ bas ically from the usual non-exact differentials. The main aim of this pa per is to examine these differences considering quasi-static irreversi ble processes with the uniformity of internal temperature and pressure . Besides, the specific heat is defined referring only to the properti es of the system and to the path of the process and not to the actual heat transfer.
