How much heat is required to melt 500 mg gold heated to its melting point? Specific heat of fusion of gold 0.67 * 10 ^ 5 J / kg
Initial data: m (mass of gold for melting) = 500 mg (500 * 10 ^ -6 kg); the gold was heated to its melting point.
Reference values: λ (specific heat of fusion of gold) = 0.67 * 10 ^ 5 J / kg.
The heat required to melt the taken gold is determined by the formula: Q = λ * m.
Calculation: Q = 0.67 * 10 ^ 5 * 500 * 10 ^ -6 = 33.5 J.
Answer: To melt 500 mg of gold, 33.5 J of heat is required.
