WebNov 17, 2024 · Thermal energy transfers occur in three ways: through conduction, convection, and radiation. When thermal energy is transferred between neighboring molecules that are in contact with one another, this is called conduction. If a metal spoon is placed in a pot of boiling water, even the end not touching the water gets very hot. WebTo reduce the amount of thermal energy transfer, we can put an air gap in between the layers. To reduce the transfer further, we can fill the gap with foam. Both of these actions will increase the thickness of the walls, therefore decreasing the thermal conductivity. Reducing Energy Waste

Being a poor conductor (non-metal) prevents heat transfer by conduction and the trapped air prevents convection currents. Related Posts: rawhide blues brothers karaoke
