This is why artificial insulators make use of air compartments, such as double-pane glass windows which are used for cutting heating bills. This is common with electrical circuits where exposed metal is a factor, ensuring that people who accidentally come into contact are not electrocuted. What does it have to do with air being poor conductor for the soup to stay hot a lot longer? In most cases, materials that are poor conductors of heat are also poor conductors of electricity. compare it to a vaccuum then it is an infinitely better conductor. Spacecraft are a special case, and use insulation in the form of foam, reinforced carbon composite material, and silica fiber tiles.

Materials that do not conduct heat as easily and quickly as metals do are bad conductors. for heat.. Air is a bad conductor because, to conduct heat current molecules should absorb heat and transmit it to neighbor by vibrating. Materials that are poor conductors of heat are called insulators.

As the convection currents (the rising of the hot air and the sinking of the cold air) keep taking place just above your soup, the previously hot soup will start to lose thermal energy (heat) and your soup will cool down despite the fact that air is a poor conductor of heat.

Convection requires the hot air just above your soup that has been heated up to rise as its density reduces after being heated, allowing the colder air around the rising hotter air to replace the hotter air and the same thing will happen again.

In the process, they bump into their neighbors and transfer the energy to them, a process which continues as long as heat is still being added. In case of air molecules near the hot surface absorbs the heat and start vibrating, but neighbor molecule is so far that this vibration should be very high and so the heat energy required is high for small conduction to start.
