When the water solidified, the amount of heat was given off 102 kJ. What is the mass of the ice formed? the specific heat of melting of ice is 3.4×10 ^ 5 J / kg.
We calculate the mass of the formed ice using the formula:
Q = λ * m, where Q is the amount of heat released into the environment (Q = 102 kJ = 102 * 10 ^ 3 J), λ is the specific heat of melting of ice (tabular value λ = 3.4 * 10 ^ 5 J / kg), m is the required mass of the formed ice (kg).
m = Q / λ = 102 * 10 ^ 3 / 3.4 * 10 ^ 5 = 0.3 kg = 300 g.
Answer: The mass of the formed ice is 0.3 kg or 300 g.
