Explain the system comes to thermal equilibrium

Reference no: EM13238260

An insulated container holds 475g of molten indium (liquid) at a temperature of 276 C. if 511g of solid indium are warmed to the melting point (157 C) and than dropped into molten indium, the system comes to thermal equilibrium at the temperature of 157 C with only liquid present. Find the heat of fusion for indium

Heat capacity of solid indium = 26.7 J mol^-1 K^-1

Heat capacity of liquid indium = 29.5 J mol^-1 K^-1

melting point of indium = 157 C

boiling point of indium = 2072 C
