GSC International N-00017 Cloth, Thermo-Sensitive Reusable. Size: 210 mm x 220 mm. Visualizing Heat Transfer Mechanisms: The thermo-sensitive cloth changes color from dark blue to pink at a temperature threshold of 30℃, providing an engaging way to visualize heat conduction and convection. By applying heat sources like a warm hand, a hot cup, or a heated surface, students can observe the flow and transfer of heat in real time.  Demonstrating Convection in Air: Using steam from hot water, students can explore how heat moves through the air via convection. The cloth’s color change highlights areas where the rising steam transfers heat to the cloth, offering a clear visual representation of convection currents.  Understanding Radiation and Heat Retention: Placing the cloth near a radiant heat source, such as a lamp or a heated metal object, allows students to observe how heat radiation affects the cloth’s temperature. Additionally, its ability to return to its original color when the heat
