WebHeat is transferred through solids via conduction. This also works in fluids, liquids and gasses, but there’s also something called “convection currents” which moves heat around inside fluids, and can transfer heat toward or away from any surface. Heat can only be transferred through a vacuum by radiation. Sponsored by The Penny Hoarder Web23 jan. 2024 · Heating is done with hot steam, which generates a temperature of exactly 100 °C when condensing on the plate. For temperature control of the cold side, a block of ice is used, which creates a temperature of exactly 0 °C on the plate during melting. This results in a temperature drop of ΔT = 100 °C along the thickness of the plate. chocolate bar proof induction
