Question

Heat transfer takes place by

A) evaporation, conduction and condensation
B) radiation, conduction and convection
C) condensation, evaporation and radiation
D) sublimation, evaporation and convection

Answer 1

Heat is transferred through conduction, convection, and radiation. Conduction involves direct contact, convection is the movement of fluid, and radiation involves electromagnetic waves.

Step-by-step explanation:

The different methods of heat transfer are conduction, convection, and radiation. Heat is transferred by conduction through stationary matter by physical contact, by convection through the macroscopic movement of a fluid, and by radiation through electromagnetic waves, such as microwaves, infrared radiation, visible light, etc. Therefore, the correct answer to the question of heat transfer taking place by which mechanisms is B) radiation, conduction, and convection.
