← ScienceWhich occurrence accompanies reversible engine isothermal gas compression?
A)Heat expulsion to the reservoir✓
B)Temperature increase above reservoir
C)Entropy decrease within the gas
D)Increased kinetic particle energy
💡 Explanation
The isothermal compression releases heat according to the first law of thermodynamics via isothermal expansion, because heat transfer maintains constant temperature to counter compression work; therefore, heat exits the system rather than raising gas temperature or decreasing entropy.
