During the melting of a slab of ice at $$273$$ K at atmospheric pressure:(i) positive work is done by the $$ice-water$$ system on the $$atmosphere(ii)$$ positive work is done on the $$ice-water$$ system by the $$atmosphere(iii)$$ the internal energy of the $$ice-water$$ system $$increases(iv)$$ the internal energy of the $$ice-water$$ system decreases

Question

Infinity Learn · Accepted Answer

During melting of ice at $$273$$ K, the ice melts to water and there is a decrease in volume.Hence atmosphere will do positive work.⇒Positive work is done on $$ice-water$$ system by the atmosphere and the internal energy of the $$ice-water$$ system increases.
