The value of CP - Cv = 1.00 R for a gas in state A and CP - Cv = 1.06 R in another state. If PA and PB denote the pressure and TA and TB denote the temperatures in the two states, then :
Answer & explanation
Correct answer: option 3
For state A : Cp - Cv = R
i.e. the gas behaves as an ideal gas.
For state B : Cp - Cv = 1.06 R (R \(\geq\)
i.e. the gas does not behave like an ideal gas.
We know that at high temperature and low pressure, nature of gas may be ideal.
So, we can sat that PA < PB and TA > TB
