Maria is cooking using a stainless steel pot. After a few minutes she notices that the pot handle is has gotten very hot. What caused the pot handle to become hot?
Answer (1)
Conduction caused the pot handle to heat up.The heat traveled through the solid metal of the pot from the hot bottom to the cooler handle. This transfer of heat through direct contact in a solid is called conduction.Key points of Conduction:When two or more objects come into direct physical contact, heat transfer takes place.When faster-moving particles (atoms or molecules) collide and impart energy to slower-moving particles in a cooler region, heat is transferred.Until thermal equilibrium is achieved when the temperatures of the two regions are equal—heat always flows from one area of higher temperature to another of lower temperature.Because the particles in solids are densely packed together, collisions can occur more frequently and energy can be transferred more effectively.Heat is transferred by conduction when two or more substances come into direct contact with one another. As the faster-moving particles in the hotter region collide with and impart energy to the slower-moving particles in the cooler region, heat energy is transferred from hotter to cooler regions.
