Bаsed оn the cоurse lectures, which оf the following stаtements аre correct with regard to heat transfer by Convection? In warmer air, the molecules are farther apart and less dense than those in cooler air causing the warm air to rise. Warm surfaces and cold surfaces that define an air space can transmit heat across the space by the phenomenon of a convective loop. Convective heat transfer occurs through electromagnetic waves. Convection is usually a combination of convective forces in a fluid medium (air) and conductive heat transfer with room surfaces at the molecular level.
