Given:
m = 200 grams = 0.2 kilograms is the mass of tin;
T = 232 degrees Celsius – tin temperature;
q = 60.7 kJ / kg = 60700 J / kg is the specific heat of fusion of tin.
It is required to determine Q (Joule) – the amount of energy required to melt the tin.
Since tin is already at the melting point (Tmelting = 231.9 degrees Celsius), the amount of heat will be equal to:
Q = q * m = 60700 * 0.2 = 12140 Joules = 12.1 kJ.
Answer: to melt tin, you need to spend energy equal to 12.1 kJ.
