Value of two principal specific heats of...

Value of two principal specific heats of a gas `("in cal mol" K)^(-1)` determined by different students are given . Which is most relible ?

A

5,2

B

6,5

C

7,5

D

7,4

Text Solution

Verified by Experts

The correct Answer is:
C
As, `C_(p)-C_(v)=R=2"cal"("mol"K)^(-1)` . Difference in the two values must be 2.
`C_(p)=7and C_(v)=5`
