| June 20, 2021 | education
Initial data: Q (the amount of heat that was reported to a piece of tin) = 177 kJ = 177 * 10 ^ 3 J.
Reference data: according to the condition λ (specific heat of fusion of tin) = 5.9 * 10 ^ 4 J / kg.
The mass of a piece of tin is determined from the formula: Q = λ * m, whence m = Q / λ.
Let’s perform the calculation: m = 177 * 10 ^ 3 / (5.9 * 10 ^ 4) = 3 kg.
Answer: The mass of a piece of tin is 3 kilograms.
