A block of ice at - 10∘C is slowly heated and converted to steam at 100∘C. which of the following curve represents the phenomenon qualitatively?
The change of ice at 10∘C into steam at 100∘C occurs in four stages; it is represented by curve (a). First stage – The temperature of ice changes from - 10∘C to 0∘C.
II Stage – Ice at 0∘C changes in water at 0∘C
The state changes as heat is supplied.
III Stage – Water at 0∘C changes into the water at 100∘C.
IV Stage – Water at 100∘C change into steam at 100∘C.
