JEE Main Solved Paper 2017 Question 12
Question: $ C _{p} $ and $ C _{v} $ are specific heats at constant pressure and constant volume respectively. It is observed that $ C _{p}-C _{v}=a $ for hydrogen gas $ C _{p}-C _{v}=b $ for nitrogen gas The correct relation between a and b is: [JEE Main Solved Paper-2017]
Options:
A) $ a=14,b $
B) $ a=28,b $
C) $ a=\frac{1}{14}b $
D) $ a=b $
Show Answer
Answer:
Correct Answer: A
Solution:
- $ C _{P}-C _{V}=R $ where $ C _{P} $ and $ C _{V} $ are molar specific heat capacities As per the question $ a=\frac{R}{2} $ $ b=\frac{R}{28} $ $ a=14,b $
