rp 1: specific heat capacity

Cards (6)

  • method rp 1:
    1. place a beaker on a balance & press 0
    2. add oil to beaker & record mass
    3. place thermometer & immersion heater into the oil
    4. read starting temp of the oil
    5. wrap beaker in insulating foam
    6. connect a joulemeter to the immersion heater
    7. leave for 30 mins
    8. read number of joules of energy that passed into the immersion heater & read final temperature of the oil
  • specific heat capacity calculation
    change in energy / mass x temperature change
  • how should u prevent thermal energy passing out of the beaker into the air?
    use an insulator with a lower thermal conductivity
  • how should u prevent not all of the thermal energy passing into the oil?
    ensure that immersion heater is fully submerged
  • how should u prevent incorrect reading of the thermometer?
    use an electronic temperature probe
  • how should u prevent thermal energy not being spread out throughout the oil?
    stir the oil
