Diagrams W, X and Y show how the particles of a substance are packed at different temperatures.

The given graph shows changes in the state of a substance on heating. In which region of the graph would all the particles be packed as in Y?

A

I

B

II

C

III

D

IV

Text Solution

Verified by Experts

The correct Answer is:
C
The given graph represents heating curve in which state of a substance changes from solid to liquid to gas.

In the given diagrams, W is a gas, X is a solid and Y is a liquid. Thus, in the region III, all the particles would be packed as in Y.
