Thermodynamics Question 228
Question: Two kg of water is converted into steam by boiling at atmospheric pressure. The volume changes from $ 2\times {{10}^{-3}}m^{3} $ to $ 3.34m^{3}. $ The work done by the system is about
Options:
A) -340 kJ
B) -170 kJ
C) 170U kJ
D) 340 kJ
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ W=P( \Delta V )=1\times 10^{5}\times ( 3.34-2\times {{10}^{-3}} ) $
$ =340\times 10^{3}J $
