Q. Which curve shows the rise of temperature with the amount of heat supplied, for a piece of ice?
A) $A$
B) $B$
C) $C$
D) $D$
Explanation
(d) Initially on heating temperature rises from $- 73℃$ (200K) to 0${^\circ}$(273K). Then ice melts and temperature does not rise. After the whole ice has melted, temperature begins to rise until it reaches 100$℃$ (373K). Then it becomes constant and after that it changes to vapours.
