Answer :
The thermal heat energy transfers through various modes. Thermoses work because they minimize conduction and radiation transfer of heat. Thus, option B is correct.
What is heat transfer?
Heat transfer has been the process that moves the heat from higher temperature towards the area of lower temperature. Conduction, convection, and radiations are the three modes of heat energy transfer.
In conduction, the heat flows from one body to another when they are in contact, and in radiation the heat flows in the waveform that does not need any direct contact. It needs an indirect medium to transfer the heat from high to lower temperatures. Thermoses do not show convection as it keeps the temperature constant.
Therefore, option B. thermoses use conduction and radiation.
