Answer:
The amount of heat require to melt the gold is 1290 J.
Explanation:
Formula:
Q = m × Lf
Q = heat required to melt the substance
m = mass of given substance
Lf = Latent heat of fusion
Given data:
Lf = 64.5 j/g
m = 20 g
Q = ?
Now we will put the values in formula.
Q = m × Lf
Q = 20 g × 64.5 j/g
Q = 1290 J
The amount of heat require to melt the gold is 1290 J.
