Answer:
Q = 1964 J
Step-by-step explanation:
Data Given:
latent heat of fusion for Lead (Lf)= 23.1 J/g
amount of ice (mass) = 85.0 gram
heat required to melt lead (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
put values in above formula
Q = mLf
Q = 85 g x 23.1 J/g
Q = 1964 J
