• What are the six steps to find specific heat capacity of a material?

  1. Turn on power supply.
  2. Measure temperature every minute for 10 minutes.
  3. Calculate power with P = VI.
  4. Calculate energy transferred with E = Pt.
  5. Plot graph.
  6. Specific heat capacity = 1 / (gradient x mass of block).
