In each of the following situations, identify the method of heat transfer taking place (conduction, convection, radiation). More than one process may be occurring. 1. Hot coffee is stirred with a spoon, the spoon gets hot due to _____. 2. A chair is placed several feet from a fire in a fireplace. The fireplace has a glass screen. The
Label each example with the appropriate type of heat transfer: radiation, convection, or conduction. Explain why you think so for each example ( hint : use the definitions above to help you). 1.
2 When the end of a rod is heated, how is the heat energy transferred across the rod? A By hot molecules moving along the rod. B By hot molecules changing places with cool ones.
As you read about the three types of heat transfer, pay attention to: What the heat is moving through (solids, liquids and gases, or empty space) How the heat is being transferred (touch, currents, or waves)
IGCSE PHYSICS (10) - TRANSFER OF THERMAL ENERGY. 3 TRANSFER OF THERMAL Energy will always try to flow from areas at high temperatures to areas at low temperatures. This is called thermal transfer. Thermal energy can be transferred in three main ways: conduction • convection • radiation.
