Question

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

Tardigrade Admin · Accepted Answer

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.

Q. If gas, at constant temperature and pressure expands then its

entropy increases and then decreases

internal energy increases

internal energy remains the same

internal energy decreases

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.
