SUMMARY
Heat transfer in the scenario of melting an ice cube in water at 0 degrees Celsius occurs primarily from the air rather than the water. This is due to the requirement of a temperature difference for heat flow; without heat from the air, the water and ice would equilibrate at 0 degrees Celsius, halting any melting process. The total entropy change of the universe is calculated using the formula ΔSuniverse = ΔSice + ΔSwater + ΔSair, indicating that all components must be considered in thermodynamic calculations.
