The difference between the principal specific heats of a gas is 300J/kg K and the ratio of its specific heats `(C_(p)/C_(v))` is 1.4. Then the value of `C_(p)` expressed in J/kg K is

A

750

B

1250

C

1050

D

500

Text Solution

Verified by Experts

The correct Answer is:

C

`C_(p)=1.4C_(v)andC_(p)-C_(v)=300`
`therefore1.4C_(v)-C_(v)=0.4C_(v)=300`
`thereforeC_(v)=(300xx10)/4=750andC_(p)=750+300=1050`
