Every single object in the universe emits and transfers thermal energy. This isn’t always useful, sometimes we want to keep hot things hot by reduce their cooling rate. Your task is to design a container which will keep a liquid warm by reducing heat transfer from the liquid to the surrounding environment.

You must incorporate features that would reduce heat loss by:

  • Conduction
  • Convection
  • Radiation
  • Evaporation

You must justify your original design for this vessel by:

  1. Explaining the scientific reasons behind why each of the features you have incorporated will reduce the cooling rate of the soup
  2. Stating which form of heat transfer the feature will reduce

There must also be a labelled diagram of your design or a labelled photograph of your prototype.
