A block of ice at `-8^(@)C` is slowly heated and converted to steam at `100^(@)C`. Which of the following curves represents the phenomena qualitatively?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
Temperature first increases from `-10^(@)`C to `0^(@)`C. Then remains constant at `0^(@)`C till whole ice is melted. Then it increases from `0^(@)`C to `100p^(@)`C. Again it remains constant at `100^(@)`C till whole water converts into steam.
