**Understanding Heat Transfer: Endothermic and Exothermic Processes** 1. **Pan on the Gas Stove** - When a pan is placed over a gas stove, the process can be categorized into two types of heat transfer: - **Endothermic Process**: The pan absorbs heat from the flame. This absorption of heat is an endothermic process because the pan gains energy. - **Exothermic Process**: The flame provides heat energy. The combustion of gas to produce a flame is exothermic, releasing heat to the surroundings, including the pan. 2. **Cooking an Egg on a Cooling Pan** - After the stove is turned off and the pan is removed, a raw egg is placed on the hot pan. In this scenario: - **Endothermic Process for the Egg**: The egg absorbs heat from the pan. This absorption results in the cooking process, making it endothermic as the egg gains heat. - **Exothermic Process for the Pan**: The pan transfers heat to the egg. As it loses heat to the surroundings (the egg), this is considered exothermic, since the pan releases energy. This exploration of heat transfer illustrates how energy is transferred between objects, resulting in either absorption (endothermic) or release (exothermic) of heat.
