A temperature of 32.5 degrees Celsius converts to approximately what temperature in degrees Kelvin?

Correct Answer: Option A — 305.5 degrees K.

Kelvin is the SI unit for absolute temperature. To convert Celsius to Kelvin, add 273.15 to the Celsius value. Calculating 32.5 + 273.15 results in 305.65, which approximates to 305.5 degrees Kelvin. Absolute temperature scales are required for accurate gas law applications in marine engine cycle efficiency calculations.
