Question

The relation between two specific heats of a gas is

• A. $C_{P} - C_{V} = \frac{R}{J}$
• B. $C_{V} - C_{P} = \frac{R}{J}$
• C. $C_{p} - C_{v} = J$
• D. $C_{v} - C_{p} = J$

Answer 1

Answer: (A)

$C_{P} - C_{V} = \frac{R}{J}$

Answer 2

When $C_{P}$ and $C_{V}$ are given with calorie and R with Joule then $C_{P} - C_{V} = R/J$.
