1550J
Explanation:
Given parameters:
Heat of fusion = 155J/g
Mass of sample = 10g
Unknown:
Quantity of heat removed to freeze the substance =?
Solution:
This is a phase change problem and we apply the formula for the specific heat of fusion to solve the problem:
Q = mL
m is the mass of the substance
L is the specific heat of fusion of the substance.
We then plug the parameters into the equation:
Q = 155J/g x 10g = 1550J
