Question

The Terich glacier in the Hindu Kush region of the Himalayas loses a volume of 1.8x10^12 L due to glacial melt.
Within a year, the summer temperature raises from 18 to 19 degrees celsius due to global warming. If the heat capacity for water and ice are 4.18 Kj/KgK and 2.11 Kj/KgK respectively, what is the change in entropy of the glacial melt? What is the change in enthalpy for the phase change?
