Kinetic Theory Of Gases Question 132

Question: The specific heat of 1 mole of an ideal gas at constant pressure $ (C _{P}) $ and at constant volume $ (C _{V}) $ which is correct

Options:

A) $ C _{P} $ of hydrogen gas is $ \frac{5}{2}R $

B) $ C _{V} $ of hydrogen gas is $ \frac{7}{2}R $

C) $ H _{2} $ has very small values of $ C _{p} $ and $ C _{V} $

D) $ C _{p}-C _{V}~=1.99cal/mole-K $ for $ H _{2} $

Show Answer

Answer:

Correct Answer: D

Solution:

[d] For any gas $ C _{P}-C _{V}=1.99\approx 2\frac{cal}{mol\text{-}K} $
