STEP 3 Most important, celebrate the victories. When weatherpeople talk about wind chill on a cold winter day, what they are referring to is how the wind increases convective heat loss (see How Thermoses Work for details on convection). Steam boilers, on the other hand, heat water past the boiling point to produce steam. In photosynthesis, sunlight and heat make chemical energy (in the form of wood or fossil fuel); fire uses chemical energy to produce light and heat. Hot rocks underground heat water to produce steam. In Living Things, the algae is the centerpoint of furniture that creates both light and food. Ovens obviously emit a tremendous amount of heat, but all that warmth doesn't stay trapped inside.
