The answer is below.

Work Step by Step

Glass is a good conductor, so it has a high thermal conductivity. However, air is a good insulator, so it has a lower thermal conductivity. Therefore, even though the layer of air is thin, the thermal conductivity of air is small enough that the heat transfer is still significantly reduced.
