heal.abstract	The isentropic change in state of an ideal gas is described using the known relations, whereby the exponent k, defined by the specific relations of thermal capacities at constant pressure and volume, is assumed to be constant. It is shown that in the case of a pvt system there are three isentrope exponents whose values differ from those of the conventional k-value. These exponents were calculated for the real gas ammonia. Therefore, in order to obtain correct results for the isentropic change in state of a real gas, the corresponding relations of an ideal gas can be applied, whereby the exponent k is replaced by one of the new exponents.	en
