[RPMT 1997]
Options:
A) 1280 J
B) 1610 J
C) 1815 J
D) 2025 J
Show Answer
Answer:
Correct Answer: C
Solution:
$ T _{2}=T _{1}{{( \frac{V _{1}}{V _{2}} )}^{\gamma -1}}=273{{(2)}^{0.41}} $
$ =273\times 1.328=363K $
$ W=\frac{R(T _{1}-T _{2})}{\gamma -1}=\frac{8.31(273-363)}{1.41-1} $
$ =-1824 $
Therefore |W| » 1815 J
