Question 318General Subjects - Assistant Engineer

The correct answer is B. Thermal energy in transition is called heat, which is the result of a temperature difference. The resulting heat flow can produce two possible outcomes - sensible heat transfer results in a change of temperature of the substance, while latent heat transfer results in a change of state of the substance. Option B accurately describes these two types of heat transfer, making it the correct answer. The other options are incorrect because they either swap the descriptions of sensible and latent heat transfer (A and D), or incorrectly state that thermal energy in transition is the result of differences in state rather than temperature difference (C).
