The table describes two methods of heat transfer. Methods of Heat Transfer Method A Method B Transfer of heat is through vibrations of the molecules of the medium Transfer of heat is through electromagnetic waves Heat is transferred in solids by this method Medium particles do not play any role in heat transfer Which statement is correct? Method A is convection and Method B is radiation. Method A is conduction and Method B is radiation. Method A is convection and Method B is conduction. Method A is conduction and Method B is convection.

Method A is conduction and Method B is radiation.

Explanation:

Driving the situation in which the heat spreads through a "conductor". That is, although it is not in direct contact with the heat source, a body can modify its thermal energy if there is heat conduction by another body, or by another part of the same body. For example, while cooking something, if we leave a spoon against the pan, which is on the fire, after a while it will heat up too.

Heat is energy in transit. This energy is transported by means of electromagnetic waves in the infrared frequency. In the transmission of heat by radiation, this fact is more evident. All bodies emit radiation, just having a temperature. The only difference between light and heat is the frequency of radiation. Thermoses are a good example of thermal radiation. The walls of the thermos are double and silver. The double walls are separated by practically a vacuum, in such a way that the heat exchanges by conduction or convection are minimized, as they need a material medium to occur. The silver walls, on the other hand, minimize heat exchanges by radiation, thus making sure that the liquid inside the bottle does not lose or receive heat.
