Answer:
2000J
Explanation:
Given parameters:
Heat of fusion = 80J/g
Mass of substance = 25g
Unknown:
Amount of energy required to melt the given mass = ?
Solution:
To solve this problem, the amount of energy required to melt the substance is given as;
H = m L
m is the mass
L is the heat of fusion
Insert the given parameters and solve;
H = 25 x 80 = 2000J
Multiple by 2 because it was give u right answer
It would have to be 40.0 only because it wouldn’t add up
The 3 and 2 to the right of the components are subscriptions.
