3] Heat transfers through the glass by conduction 4] Heat transfers from the glass to the outside air via convection. If the temperature differences are small and there are no winds or drafts, transfer of heat to/from air/glass will be by conduction.
A: Brightstorm explains that thermal energy transfer involves the internal transfer of energy, of which there are three major types: conduction, radiation and convection. When there is a temperature difference between the involved systems, heat transfers from the hotter system to the cooler system, which is why hot drinks become cold. Continue Reading
