1.	A diatomic ideal gas initially at 273 K is given 100 cal heat due to which system did 209 J work. Molar heat capacity ` (C_(m))`n of gas for the process is :A. `(3)/(2) R`B. `(5)/(2) R`C. `(5)/(4)R`D. 5 R
Answer» Correct Answer - D `DeltaU = 100 -(209)/(4.18) = 50 cal rArr DeltaU = nC_(V)dT rArr C_(v,m) = (5)/(2)R rArr ndT = (20)/(R) rArr q = nC_(m) dT` `C_(m)= (100R)/(20) R`
