1.	Equal volumes of monoatomic and diatomic gases a same initial temperature and pressure are mixed.The ratio of specific heats of the mixture `(C_(p)//C_(v))`will beA. `1`B. `2`C. `1.67`D. `1.5`
Answer» Correct Answer - A `C_(v)=(3)/(2)RT,C_(P)=(5)/(2)RT` for monoatomic gas `C_(v)=(5)/(2)RT,C_(P)=(7)/(2)RT` for monoatomic gas Thus for mixture of 1 mole each, `C_(v)=((3)/(2)RT(5)/(2)RT)/(2)` and `C_(p)=((5)/(2)RT(7)/(2)RT)/(2)` Therefore, `C_(p)//C_(v)=(3RT)/(2RT)=1.5` .
