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 conduction.
2. A chair is placed several feet from a fire in a fireplace. The fireplace has a glass screen. The side of the chair facing the fireplace gets warm because of radiation.
3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break off and rise to the top of the liquid. The globs rise due to convection.
4. Near the ceiling of a room, the air is warmer. The warm air rises because of convection.
5. A college student holds the back of his hand near an iron to see if it is hot. Heat is transferred to his hand by conduction.
