Three methods of heat transfer are?

• A. Convection, Conduction and Radiation
• B. Conduction, Radiation and Evaporation
• C. Conduction, Convection and Evaporation
• D. Radiation, Evaporation and Condensation

Answer: (A)

Heat moves in three ways: conduction, convection, and radiation. Conduction happens when heat travels through touching substances or within a solid as particles transfer energy directly. Convection involves the movement of heat by the flow of a fluid, like air or water, with currents carrying energy from warmer to cooler areas. Radiation is heat transfer through electromagnetic waves, so warmth can reach you from a fire even across space without needing air or contact. Evaporation is a phase-change process that uses latent heat, but it isn’t one of the fundamental methods of heat transfer. It can occur alongside the three modes, not replace one of them. That’s why conduction, convection, and radiation are the correct trio.
