Thermal management systems and physical phenomena rely on distinct thermodynamic processes to transfer or absorb energy. Match each thermal phenomenon or device on the left with the primary thermodynamic principle that explains its operation on the right.
- Rapid cooling of an aerosol canister nozzle during continuous sprayingAdiabatic expansion of gas doing work against external pressure, decreasing internal thermal energy
- Industrial cooling tower lowering water temperature via evaporationAbsorption of latent heat of vaporization from the surroundings during liquid-to-gas phase transition
- Evacuated double-wall flask preventing temperature change of stored liquidsElimination of a material medium to prevent conductive and convective heat transfer
- Aluminum finned heat sink attached to an electronic microprocessorIncreasing exposed surface area to maximize convective and radiative heat dissipation to ambient air
Answer
Aerosol canister cooling matches adiabatic expansion doing work and decreasing internal energy; Cooling tower matches absorption of latent heat of vaporization during liquid-to-gas phase change; Evacuated double-wall flask matches elimination of a material medium to stop conduction and convection; Aluminum finned heat sink matches increasing surface area to maximize convective and radiative dissipation.
Each application precisely maps to its foundational thermodynamic mechanism: aerosol discharge is an adiabatic expansion lowering temperature; cooling towers utilize latent heat of vaporization; vacuum flasks eliminate the physical medium to block conduction and convection; and finned heat sinks expand surface area to enhance fluid convection.
