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.
A
1466Jkg-1 oC-1
B
2933Jkg-1 oC-1
C
4400Jkg-1 oC-1
D
5866Jkg-1 oC-1
Verified Correct Answer: A.
Physical Principles & Numerical Solution
22,000 = 1.5 x c x (30 - 20)
c = 1466Jkg-1 oC-1
