Chemical Thermodynamics Question 235
If gas, at constant temperature and pressure expands then its volume increases [MH CET 2003]
Options:
A) Entropy increases and then remains constant
B) Internal energy increases
C) Internal energy remains the same
D) Internal energy decreases
Show Answer
Answer:
Correct Answer: C
Solution:
We know that internal energy of a gas depends upon its temperature and not on its pressure. Thus if a gas expands at constant temperature and pressure, then its internal energy remains same.
