Specific Heat Capacity

• Apparatus: Solid block, Drill, Thermometer, Heater (of known power), Cotton wool.
• Procedure:

  • Drill two holes in the block.
  • Measure the mass of the block.
  • Place the heater in one of the holes, the thermometer in the other.
  • Use cotton wool to properly insulate/lag the block.
  • Note the initial temperature of block and turn on heater for x seconds
  • Calculate Heat Energy Supplied by heater using formula Q=Pt.
  • Note the final temperature of block.
  • Specific heat capacity = Q/mΔT
