22,000J of heat is required to raise the temperature of 1.5kg of paraffin from 20oC to 30oC. Calculate the specific heat capacity of paraffin.

  • 1466Jkg-1 oC-1 checkmark
  • 2933Jkg-1 oC-1
  • 4400Jkg-1 oC-1
  • 5866Jkg-1 oC-1

The correct answer is: A

Explanation

22,000 = 1.5 x c x (30 - 20)

c = 1466Jkg-1 oC-1
