← ScienceWhich phenomenon limits maximum work in isothermal engine?
A)Entropy increases due to heat waste✓
B)Pressure remains constant along isotherm
C)Volume remains constant during cooling
D)Kinetic energy remains uniformly distributed
💡 Explanation
Entropy causes increased heat waste inside any real engine because the Second Law of Thermodynamics constrains energy available for work. Therefore, usable energy decreases due to rising entropy, rather than being prevented by constant volume.
