As , C p- C V =R=4150 J / kg - K and ( C p/ C V )=&gamma;=1.4 C V=(R/&gamma;-1)=(4150/(1.4-1)) =10375 J / kg - K

Q. For a gas the difference between the two specific heats is $4150 J / k g - K$ . What is the specific heats at constant volume of gas it the ratio of the specific heat is $1.4$ ?

$8475 J / k g - K$

$5186 J / k g - K$

$1660 J / k g - K$

$10375 J / k g - K$

$A s, C_{p} - C_{V} = R = 4150 J / k g - K$
and $\frac{C _{p}}{C _{V}} = γ = 1.4$
$C_{V} = \frac{R}{γ - 1} = \frac{4150}{( 1.4 - 1 )}$
$= 10375 J / k g - K$
