Determine how much heat is needed to melt 1.1 kg of tin at a melting point of 232 ° C. The specific heat of fusion of tin is 0.59⋅10 ^ 5Jkg.
Given:
m = 1.1kg
t = 232
Decision:
Specific heat of fusion formula:
Q = λ * m
We replace the letters with our data:
Q = 0.59 10⁵ 1.1 = 64900 J
We translate into kJ: 64900 J = 64.9 kJ.
Answer: 64.9 kJ.
