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 $10375J/kg-K$

We know that,
$C_p-C_V=nR$
$C_p/C_V=1.4$
$C_p-C_V=4150$
$0.4C_V=4150$
$C_V=4150/0.4$
$C_V=10375$
Hence option(D)
