Heat & thermodynamics › Heat-transfer visualiser
Heat-transfer laboratory
Compare materials and watch thermal energy move by conduction, convection and radiation.
What to notice
Heat flows from hotter regions towards colder ones. Conductive materials spread temperature changes quickly, while insulation adds thermal resistance. Convection exchanges heat with moving fluid, and radiation transfers energy electromagnetically without requiring a material medium.
