The transfer of heat by the movement of heated fluid is called conduction.
a. true
b. false

The answer to this question is, B. False. The transfer of heat by the movement of heated fluid is called convection. Convection deals with the flow of hot air and fluids. As they disperse, they carry with them the thermal energy and spread it out towards the cooler air and fluids.
