WebAboutTranscript. There are three forms of thermal energy transfer: conduction, convection, and radiation. Conduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated. Thermal radiation happens when accelerated charged particles ... WebAir is a poor conductor, (k=0.02 Wm-1 K-1), and so each layer acts like the fibre-glass in producing a large reduction in heat loss. The calculation above assumes that the temperature of the window surfaces is that of the air, and implies a ‘temperature profile’ across the air-glass-air to be like: A more realistic temperature profile is:
