Answer

C. A spoon heats up while sitting in a bowl of soup.<br /><br />Conduction is the transfer of heat through direct contact. The hot soup directly contacts the spoon, transferring heat and causing the spoon's temperature to rise.<br /><br />The other options describe different methods of heat transfer:<br /><br />* **A. A cat warms up by sitting in a patch of sunlight:** This is radiation, where heat is transferred through electromagnetic waves.<br />* **B. The warm Gulf Stream warms the European coast:** This is convection, where heat is transferred through the movement of fluids (liquids or gases).<br />* **D. You cool off by standing in a cool breeze:** This is also convection, with the breeze carrying away your body heat.<br />
