What is the mass of a silver ingot that can be melted at the melting temperature by transferring to it an amount of heat of 29 kJ
Initial data: Q (the amount of heat that was transferred to the silver ingot during melting) = 29 kJ (29 * 10 ^ 3 J).
Reference values: λ (specific heat of fusion of silver) = 0.87 * 10 ^ 5 J / kg.
The mass of a silver bar can be expressed from the formula: Q = λ * m and m = Q / λ.
Calculation: m = 29 * 10 ^ 3 / (0.87 * 10 ^ 5) = 0.333 kg (333 g).
Answer: The molten silver bar weighed 333 grams.
