The objective of this experiment is apply the adiabatic expansion method for determining the spec$c heat capacity ratio of gas <span>N2 </span>and <span>O2 </span>The result showed that the ratio were 1.14 and 1.19 respectively for gas <span>N2 </span>and <span>02.</span>T he value obtained by the experiment was d~flerenta bout 15 to 19% from the result determined by theoretical method </span><span style="font-family:Courier;">using </span><span>5 </span><span style="font-size:11.5pt;">degree of Jkeedom. Theoretically cdc,, of both gas <span>N2 </span>and </span><span style="font-size:7.5pt;">0 2 </span><span style="font-size:11.5pt;">which have 5 degree offreedom are 1.4. The dzflerence was considered to be caused by thee xperimental</span><span> </span><span style="font-size:11.5pt;">condition, which were not suflciently adiabatic, as required </span><span>by </span><span style="font-size:11.5pt;">the method. However, the simplicity of the method and clarity of its theoretical approach </span><span style="font-size:12pt;">is </span><span style="font-size:11.5pt;">advantageous to be used by students of Advance Thermodynamic class as a practical exercise.</span></p> Download Download PDF
