Thermodynamics Question 137
Question: If $ C _{V}=4.96cal/mole $ K, then increase in internal energy when temperature of 2 moles of this gas is increased from 340 K to 342 K
[RPET 1997]
Options:
A) 27.80 cal
B) 19.84 cal
C) 13.90 cal
D) 9.92 cal
Show Answer
Answer:
Correct Answer: B
Solution:
$ \Delta U=\mu C _{V}\Delta T=2\times 4.96\times (342-340)=19.84\ cal $
