Q. In a closed piston-cylinder system, methane was observed to obey the following equation of state
P(V– nb) = nRT
where b = 0.029 m3/mol. The temperature and volume are 500 ºC and 5 m3 respectively for 100 moles of methane. At this state of the system, the isobaric rate of change of temperature with volume (in ºC/m3) is
Ans: 367 to 369
