Question

An ideal gas undergoes isothermal process from some initial state $i$ to final state $f$. Choose the correct alternatives.

• A. $dU=0$
• B. $dQ=0$
• C. $dQ=dU$
• D. $dQ=dW$

Answer 1

Answer: (A), (D)

The correct options are
A $dU=0$
D $dQ=dW$

Internal energy is a function of temperature. Since temperatue is constant $dU=0$
