    Difficulty: Easy
    • Kelvin
    • Rankine
    • Fahrenheit
    • Celsius
  2. This law states that energy cannot be created or destroyed, only transformed from one form to another.

    Difficulty: Medium
    • Second law of thermodynamics
    • First law of thermodynamics
    • Third law of thermodynamics
    • Zeroth law of thermodynamics
  3. This principle states that the minimum work required to erase one bit of information at temperature T is kT ln(2).

    Difficulty: Hard
    • Landauer's principle
    • Von Neumann's theorem
    • Shannon's theorem
    • Boltzmann's principle
  4. When you rub your hands together on a cold day, you convert mechanical energy into this form of energy.

    Difficulty: Easy
    • Heat
    • Sound
    • Light

  5. This second-law impossibility states that no cyclic device can convert heat completely into work without any other effect.

    Difficulty: Medium
    • Carnot statement
    • Kelvin-Planck statement
    • Boltzmann statement
    • Clausius statement
  6. This series expansion expresses compressibility factor Z as 1 + B/V + C/V² + ..., with coefficients encoding molecular pair and triplet interactions.

    Difficulty: Hard
    • Van der Waals equation
    • Redlich-Kwong equation
    • Peng-Robinson equation

  7. Hot air rising from a radiator and cool air sinking toward the floor demonstrates this circular heat transfer pattern.

    Difficulty: Easy
    • Conduction
    • Radiation
    • Convection
    • Diffusion
  8. This idealized gas model assumes particles have no volume and no intermolecular forces, making PV = nRT exact.

    Difficulty: Medium
    • Van der Waals gas
    • Real gas
    • Ideal gas
    • Perfect crystal
