During the melting of a slab of ice at 273K at atmospheric pressure:
1
positive work is done by the ice-water system on the atmosphere and the internal energy of icewater system decreases.
2
positive work is done on the ice-water system by the atmosphere and the internal energy of the ice-water system increases
3
only the internal energy of the ice-water system increases
4
only the internal energy of ice-water system decreases.
