SHC

Cards (6)

  • step 1 :
    place beaker on top pan balance and measure out 1000g of vegatable oil
  • step 2 :
    place thermometer in the beaker with oil, record starting temperature and insulate the beaker
  • step 3:
    place the beaker on an electric heater and turn on the joule metre, then turn on the heater and start a timer
  • step 4:
    every minute record the joules on the joulemeter for 10 minutes and after turn off the heater, joulemeter and timer
  • step 5:

    record the final temperature and calculate the change in temperature (final - start) and calculate the mean number of joules of the energy (sum of all recorded/ 10)
  • step 6 :
    calculate the SHC of the oil by using the equation: energy/ mass x change in temp
