Question

The graph below represent the heating curve of substance X.
i) What part of the curve represents liquid phase of substance X?

ii) Identify the melting point of substance X?

iii) In what part of the curve would the molecules of substance X have more inter

molecular space?

iv) In what part of the curve would the molecules of substance X are closely packed?​

Answer 1

Answer:

(I) III
