Selected thermochemical properties of substances and their graphic web presentation

The contribution is devoted to graphic web presentation of selected thermochemical properties, e.g. molar heat capacity courses, using service oriented architecture (SOA) and web service for thermodynamic calculation support. In the introduction paper specifies graphic support (GD library). Solution of application is based on taking advantage of graphic support JpGraph and mentioned web service. There were created two specialized functions for parameters check, control of calculation using web service, filing their results into arrays and their depiction in graphic form. Application interface consists of parameters for identification of web service, substance, temperature´s scope and step, graph size and x-axis ticketing density as well as if appropriate of file name in which calculated graph course will be in jpg format. There are presented examples of molar heat capacity courses for selected substances.
