RT Journal Article SR Electronic A1 FILÍPEK, Josef T1 STATUS CHANGE SIMULATION IN IDEAL GAS JF Trends in education YR 2015 VO 8 IS 1 SP 62 OP 70 UL https://tvv-journal.upol.cz/en/artkey/tvv-201501-0026.php AB In closed thermodynamic setup three magnitudes change with heating, cooling and external force effects - volume, pressure and temperature. Therefore it is suitable to visualize state changes in spatial diagram (on thermodynamic plane). Multimedia project, which is a base of this article, graphically describes the course of state and energy magnitudes in ideal gas.
