Thermodynamics Question 252
Question: During an adiabatic process of an ideal gas, if P is proportional to $ \frac{1}{{{V}^{1.5}}} $ , then the ratio of specific heat capacities at constant pressure to that at constant volume for the gas is
Options:
A) 1.5
B) 0.25
C) 0.75
D) 0.4
Show Answer
Answer:
Correct Answer: A
Solution:
[a] As $ $ $ \therefore \gamma \text{=1}\text{.5}( \therefore \text{Process is adiabatic} ) $
As we know, $ \frac{C _{P}}{C _{V}}=\gamma \text{ }\therefore \frac{C _{P}}{C _{V}}=5\text{ } $
