Answer:
56.7 KJ
Explanation:
Data Given:
latent heat of fusion for water (Lf)= 333.4 J/g
amount of ice (mass) = 170 gram
heat required to melt ice (Q) =?
Solution:
Latent heat of fusion: the amount of heat that required to melt certain amount of a substance. The total heat absorbed by substance is proportional to the total heat of fusion of the material.
Formula Used
Q = mLf
Q = heat required to melt a substance
m = mass of the substance
Lf =latent heat of fusion also denoted by ΔHf
put values in above formula
Q = mLf
Q = 170 g x 333.4 J/g
Q = 56678 J
convert J to KJ
1000 J = 1 KJ
56678 J = 56678 /1000 = 56.678 KJ
Q ≅ 56.7 KJ
