Thermodynamics Question 296
Question: A system changes from the state $ (P _{1},V _{1}) $ to $ (P _{2},V _{2}) $ as . What is the work done by the system?
Options:
A) $ 7.5\times 10^{5}joule~ $
B) $ 7.5\times 10^{5}erg $
C) $ 12\times 10^{5}joule $
D) $ 6\times 10^{5}joule $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ ~W=W _{1}+W _{2} $
$ -p _{0}(\gamma -1)+\alpha (\gamma -1)V=p _{0}-2\alpha V $
$ =12\times 10^{5}\text{joule} $
