The sun hits the Earth providing 172 W per square meter. A 1.29 m2 patch of a solid sample with an initial temperature of -3.80 °C is placed under the sun for 15.0 hours. If the sunlight uniformly penetrates the sample to a depth of 1.50 cm and it does not melt, what will be its final temperature? (enthalpy of fusion of liquid sample = 6.01 kJ/mol, specific heat capacity of solid sample = 2.032 J/g°C)
