0.5kg of water at 10oC is completely converted to ice by extracting 188000J of heat from it. If the specific heat capacity of water is 4200J kg-1C-1, calculate the specific latent heat of fusion of ice.
-
A.
9.0 KJ kg-1 -
B.
84.0 KJ kg-1 -
C.
168.0 KJ kg-1 -
D.
334.0 KJ kg-1 -
E.
336.0 KJ kg-1
Correct Answer: Option D
Explanation
Q = mcΔθ = (0.5 x 4200 x 10) + 0.5L
L = 334000
