First law of thermodynamics: When a fixed amount of ideal gas goes through an adiabatic expansion,

Question

Quizplus · Accepted Answer

The first law of thermodynamics, which is a statement of conservation of energy, implies that in an adiabatic process (where no heat enters or leaves the system), any work done by the gas must come from its internal energy. Therefore, option C is correct because it directly states that no heat enters or leaves the gas during an adiabatic expansion.
