B
The change of ice at −10∘C into steam at 100∘C occurs in four stages.- The temperature of ice changes from −10∘Cto0∘C.
- Ice at 0∘C changes to water at 0∘C. The state changes as heat is supplied.
- Water at 0∘C changes into water at 100∘C.
- Water at 100∘C change into steam at 100∘C.The state changes as heat is supplied.
