Which one of the following is applicable for an adiabatic expansion of an ideal gas?
- A \(\Delta E=0\)
- B \(\Delta W = \Delta E\)
- C \(\Delta W = - \Delta E\)
- D \(\Delta W = 0\)
Answer & Solution
Correct Answer
(B) \(\Delta W = \Delta E\)
Step-by-step Solution
Detailed explanation
\(\Delta E=q+W\) For an adiabatic reaction, \(\Delta q=0\) So, \(\Delta E=\Delta W\)
