Heat Transfer in Nature
A steel spoon grows hot in tea, sea breezes change direction by day and night, and sunshine warms us from afar, and this chapter of the NCERT Curiosity textbook for Class 7 explains all three paths. It describes conduction through solids, convection through moving water and air, and radiation that needs no medium, with sea and land breezes as living examples. Experiments with rods, water, and warm surfaces let learners feel each process, and the chapter ends with why woollen clothes and vessel handles behave as they do.
