RT Journal Article SR Electronic A1 FILÍPEK, Josef A1 NAVRÁTIL, Miroslav T1 CONNECTION OF ANIMATION AND MATHEMATICS FOR DESCRIPTION OF IDEAL GAS STATE CHANGES JF Trends in education YR 2009 VO 2 IS 1 SP 424 OP 427 UL https://tvv-journal.upol.cz/en/artkey/tvv-200901-0097.php AB The paper presents continuous changes of state quantities of ideal gas during isothermal and adiabatic compression depending on the degree of external force. Mutual relationships are illustrated with the use of animated models, spatial and area diagrams, including mathematical derivation of the volume work performed by the system.
