Goal: Problem solving with thermal energy.

Source: UMPERG-ctqpe208

A cup of water is about 225 grams. The minimum amount of heat needed to
boil a cup of water at room temperature for tea is most nearly

  1. 10,000 cal
  2. 17,000 cal
  3. 25,000 cal
  4. 31,000 cal
  5. None of the above
  6. Cannot be determined



(2) This problem requires that students know the specific heat of water
and assume that the water is initially at room temperature.
