| Determine how much heat will be released during the crystallization of 3.1 liters of mercury. The specific heat of crystallization of mercury is 0.12⋅105 J / kg, the density of mercury is 13600 kgm3.
Given: V = 3.1L, [lambda] = 0.12 * 10 ^ 5 J / kg, p = 13600 kg / m ^ 3
SI: V = 0.0031 m ^ 3
Find: Q
Decision:
1. Q = [lambda] m
m = pV
m = 13600 kg / m ^ 3 * 0.0031 m ^ 3 = 42.16 kg
Q = 0.12 * 10 ^ 5 J / kg * 42.16 kg = 505920J
Answer: Q = 505920J
