Answer
Heat Energy left the tea and went into the spoon through conduction.**Explanation:**Conduction is the transfer of heat energy through direct contact between molecules within a substance or between substances in contact. The hot tea molecules are vibrating rapidly. When the cold spoon touches the tea, the rapidly vibrating tea molecules collide with the slower-moving spoon molecules. This transfers energy to the spoon's molecules, causing them to vibrate faster and thus increasing the spoon's temperature. Convection involves the transfer of heat through the movement of fluids (liquids or gases), which isn't the primary mechanism at play here.
