WebWhen heat is transferred to an object by its surroundings, then the object can warm up and the surroundings can cool down. Heat, once absorbed as energy, contributes to the overall internal energy of the object. One form of this internal energy is kinetic energy; the particles begin to move faster, resulting in a greater kinetic energy. WebHeat is initially transferred from the Bunsen flame through the glass wall of the beaker by conduction. The water in the region of the Bunsen flame is heated. It expands, becomes less dense...
