Hot Stuff: Heat, Temperature and Cooling

Does hotter always mean more heat? Why is sand too hot to stand on while the sea is cool? Why does a drink cool fastest at the start? How do you keep it hot? Four quantitative lessons with thermometers and a kitchen scale: Q = mcΔT, specific heat capacity, Newton's law of cooling and a drink-keeper design problem, with uncertainty throughout.

  1. Does hotter always mean more heat?
  2. Why is the sand too hot to stand on when the sea is still cool?
  3. Why does a hot drink cool fastest at the start?
  4. How do you keep a drink hot for the longest?
