SCIENCE:
2. Explain how heat is transferred from the stove to the pan in the model and how thermal energy is being transferred (including on the molecular level)
3. Label your model
4. Write in complete sentences how the stove to the pan transfers thermal energy and the impact it has on the physical properties of the substance you are using in the “Write” portion of the paper.
2. In the model, heat is transferred from the stove to the pan through a process called conduction. Conduction occurs when heat energy is transferred from one molecule to another through direct contact. In this case, the molecules at the bottom of the pan directly contact the heat source (stove) and gain thermal energy. This increase in thermal energy causes the molecules to move faster and vibrate more vigorously.
On a molecular level, the stove transfers thermal energy to the pan through the collision of high energy molecules from the stove with the low energy molecules in the pan. When the high energy molecules collide with the low energy molecules, they transfer some of their energy to the pan's molecules, causing them to gain thermal energy.
3. The model can be labeled as "Heat Transfer: Stove to Pan through Conduction."
4. The transfer of thermal energy from the stove to the pan through conduction affects the physical properties of the substance being used, which in this case is the material of the pan itself. As the thermal energy is transferred, the molecules of the pan material gain kinetic energy and vibrate at a higher frequency. This increase in molecular motion leads to an increase in temperature of the pan.
Furthermore, as the pan heats up, its physical properties may change. For example, if the pan is made of a metal, the expansion of the metal due to the increased temperature can cause the pan to slightly change its shape. Additionally, materials like non-stick coatings on the pan may be affected by the heat, potentially causing them to degrade or release volatile compounds. Overall, the transfer of thermal energy from the stove to the pan alters the physical state and properties of the substance being used, which is the pan in this case.
