The THREE modes of heat transfer are:
A{'text': 'Diffusion, advection, dispersion', 'label': 'A'}
B{'text': 'Conduction, Convection, Radiation', 'label': 'B'}
C{'text': 'Latent, sensible, total', 'label': 'C'}
D{'text': 'Forced, free, mixed', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': 'Conduction, Convection, Radiation', 'label': 'B'}
Three fundamental modes: (1) Conduction — molecular diffusion through matter, no bulk motion. (2) Convection — bulk fluid motion carries heat. (3) Radiation — electromagnetic waves, no medium needed.
