When an icicle melts at 2 degrees Celsius, the change in entropy is positive because the phase transition from solid (ice) to liquid (water) increases the disorder of the system. The melting process absorbs heat, and since the melting occurs at a constant temperature, the entropy change can be calculated using the formula ΔS = Q/T, where Q is the heat absorbed and T is the absolute temperature in Kelvin. As ice transitions to water, the increase in molecular freedom contributes to the overall increase in entropy.
