Chemical Thermodynamics Question 460

Question: One mole of an ideal gas is allowed to expand reversibly and adiabatically from a temperature of 27oC . If the work done during the process is 3 kJ, the final temperature will be equal to (Cv=20,JK1)

Options:

A) 150 K

B) 100 K

C) 26.85oC

D) 295 K

Show Answer

Answer:

Correct Answer: A

Solution:

  • We know that work done, W=Cv(T1T2)

3×1000=20,(300T2) ;
3000=600020,T2

T2=300020=150,K .
