Answer :
Thermoses work by minimizing heat transfer through all three modes of heat transfer (d) conduction, convection, and radiation.
The walls of a thermos are typically made of two layers of glass with a vacuum in between, which helps to minimize heat transfer by conduction and convection. The vacuum reduces the amount of air molecules present, which can conduct heat, and also reduces the ability for heat to be transferred by convection.
Additionally, the walls of the thermos are often coated with a reflective material to reduce the amount of heat transferred by radiation. By minimizing all three modes of heat transfer, thermoses are able to keep the contents inside at a constant temperature for a longer period of time.
