The heat dissipated by from a surface depends upon its temperature and its characteristics like colour, roughness etc?
Correct answer: C. radiation
- A. conduction
- B. convection
- C. radiation
- D. any of the above
Explanation
Radiation depends strongly on the surface temperature and emissivity, which is affected by colour, roughness and surface finish. Conduction requires a material path, while convection requires moving or circulating fluid.
