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-1oC-1 -
B.
2933Jkg-1oC-1 -
C.
4400Jkg-1oC-1 -
D.
5866Jkg-1oC-1
Correct Answer: Option A
Explanation
22,000 = 1.5 x c x (30 – 20)
c = 1466Jkg-1oC-1
