Day 15

  1. higher for the Fe sample, because with its lower specific heat it absorbs more energy
  2. higher for the Al sample, because with its higher specific heat it absorbs more energy
  3. the same for both metal samples, because the initial and final temperatures are the same
  4. the same for both metal samples, because the masses are equal

Samples of Fe and Al are heated from 25C to 75C. Based on the information in the table to the right, the change in the average kinetic energy of the atoms in the samples is
