What statement is true concerning thermal energy in transition?

Correct Answer: Option B — Thermal energy in transition is called heat which is the result of a temperature difference. The resulting heat flow may produce two possible outcomes. Sensible heat transfer results in a change of temperature of the substance. Latent heat transfer results in a change of state of the substance.

Heat transfer driven by temperature gradients manifests as sensible heat, causing temperature changes without phase shifts, or latent heat, causing phase changes at constant temperatures. This distinction is vital for managing heat exchangers, steam systems, and refrigeration cycles aboard vessels as per standard thermodynamic principles.
