Form 9: Surface Color, Texture, and Thermal Radiation

In this interactive exercise, students will explore how surface color and texture affect thermal radiation absorption and emission, engaging in hands-on experiments with various materials to discover the science behind heat transfer. Through observation and analysis, learners will deepen their understanding of thermal dynamics in real-world applications.
