If gas, at constant temperature and pressure expands then its.
A
Entropy increases and then decreases
B
Internal energy increases
C
Internal energy remains the same
D
Internal energy decreases
Answer
Internal energy remains the same
Explanation
Solution
We know that internal energy of a gas depends upon its pressure and temperature. Thus if a gas expands at constant temperature and pressure, then its internal energy remains same.
