Question
A block of ice at $$ - {10^ \circ }C$$ is slowly heated and converted to steam at $${100^ \circ }C.$$ Which of the following curves represents the phenomenon qualitatively?
A.
B.
C.
D.
Answer :
Solution :
1. The temp. of ice changes from $$ - {10^ \circ }C$$ to $${0^ \circ }C.$$
2. Ice at $${0^ \circ }C$$ melts into water at $${0^ \circ }C.$$
3. Water at $${0^ \circ }C$$ changes into water at $${100^ \circ }C.$$
4. Water at $${100^ \circ }C$$ changes into steam at $${100^ \circ }C.$$
