    Supports→A dissipative measurement using light to detect the molecule's location precludes a net conversion of heat into work in Szilard's engine.

    Bennett's 1982 analysis of Maxwell's Demon demonstrates that the demon's memory must be reset between cycles, and this erasure dissipates exactly the work gained from isothermal expansion.

    Key Terms

    Bennett(as the scientist whose work is being discussed)
    Charles Bennett is a physicist who made major discoveries about the relationship between information, energy, and thermodynamics. In this context, he's famous for proving that the act of measuring something doesn't have to waste energy.
    Erasure(contrasted with acquiring information)
    In this context, the act of deleting or destroying information stored in a physical system.
    Isothermal expansion(the process from which the demon gains energy)
    A process where a gas spreads out into a larger space while staying at the same temperature; this process normally produces useful work or energy.
    Maxwell's demon(as used in physics and thermodynamics)
    A thought experiment about an imaginary tiny creature that could supposedly violate the second law of thermodynamics by sorting fast and slow molecules to create energy from nothing.

    Memory reset(describing what the demon must do between cycles)
    The process of erasing or clearing information that the demon has stored, returning it to a blank state so it can repeat its work.
    Thermodynamics (second law of)(the physical principle Bennett's work relates to)
    A fundamental rule of physics stating that disorder and heat always increase over time in closed systems, making it impossible to create energy from nothing.
