Question

what is the change in entropy when an icicle melts at 2°c

Answer 1

Answer:

The entropy of the system, which is δQ/T, increases by δQ/273K. The heat δQ for this process is the energy required to change water from the solid state to the liquid state, and is called the enthalpy of fusion, i.e. ΔH for ice fusion

Answer 2

Answer:

The entropy of the system, which is Q/T, increases by Q/273K. The heat Q for this process is the energy required to change water from the solid state to the liquid state, and is called the enthalpy of fusion, i.e. ΔH for ice fusion.
