For a gas the differce between the two specific heat is `4150 J//kg K`. What is the specific heat at constant volume of gas if the ratio of sepcific heat is 1.4A. 8475B. 5186C. 1660D. 10375

Answer» Correct Answer - D
`C_(p)-C_(V)=R and C_(p)//C_(V)=1.4`
`therefore C_(p)=1.4C_(V) " "therefore 1.4C_(V)-C_(V)=R`
`therefore0.4C_(V)=R`
`C_(V)=(4150)/(0.4)=(41500)/(4)`
`=10375`
