For a certain gas the ratio of specific heat is 1.5, for thisg gas :

Answer»

`C_(p)=(5R)/(J)`
`C_(v)=(3R)/(J)`
`C_(v)=(5R)/(J)`
`C_(p)=(3R)/(J)`

Solution :`(C_(p))/(C_(v))=1.5=(3)/(2)`
or `C_(p) =(3)/(2) C_(v)`
`C1_(v)=(2)/(3) C_(p)`
Now `C_(p) -C_(v) =(R )/(J)`
`therefore C_(p) -(2)/(3) C_(p) =(R )/(J)`
`therefore C_(p) =(3R)/(J)`
`therefore` Correct choice is (B).
