1.	Assume ideal gas behavior for all the gasesconsidered and vibratonal degree of freedom to be active. Separated equimolarsample of Ne,O_(2), So_(2) and CH_(4)were subjedted to a two step process as mentioned . Initiallytall areat samestate of temperture and pressure.Step -I:All undergo reversibleabiabatic expansion to attainsame finalvolume therebycausingthedecreasae in theirtemperature.Step -II:Afterstep I, allare given appropriate amount of heat isochoricallyto restorethe originaltemperature . Mark the correct optoin(s).
Answer» Due to step Ionly , the decrease in temperature will be maximumfor Ne. During step II , heat given will be minimumfor `CH_(4)` There will be no NET change in INTERNAL ENERGY for any of the gas after boththe steps of process are completed. The `(@) P-V` GRAPH of `CH_(4)` and `SO_(2)` wll be same for overall process. Answer :a,c
