Question

For a gas the difference between the two specific heats is $4150J/kg-K$. What is the specific heat at constant volume of gas if the ratio of specific heats is 1.4

• A. $8475J/kg-K$
• B. $5186J/kg-K$
• C. $1660J/kg-K$
• D. $10375J/kg-K$

Answer 1

The correct option is D $10375J/kg-K$

It is given that $C_P-C_V=4150J/kg-K$.........Equation 1

and $\frac{C_P}{C_V}=1.4$.........Equation 2

Thus solving the two equations gives:

$C_V=10375J/kg-K$
