Chemical Thermodynamics Question 343
Question: Which of the following statements/relationships is not correct in thermodynamic changes-
Options:
A) $ \Delta U=0 $ (isothermal reversible expansion of a gas)
B) $ w=-nRT $ In $ \frac{V_2}{V_1} $ (isothermal reversible expansion of an ideal gas)
C) $ w=nRT $ In $ \frac{V_2}{V_1} $ (isothermal reversible expansion of an ideal gas)
D) For a system of constant volume heat involved directly changes to internal energy.
Show Answer
Answer:
Correct Answer: C
Solution:
For isothermal reversible expansion. $ w=-nRT,ln\frac{V_2}{V_1} $
