| Heating curve for water is shown below. |
 |
| Now, choose the correct option. |
A) Length B is larger than length D as average distance between two liquid molecules is much less than distance between two gas molecules
B) Length B is equal to length D as average distance between two liquid molecules is much less than distance between two gas molecules
C) Length B is less than length D as average distance between two liquid molecules is much less than distance between two gas molecules
D) Length B can be less or more than D depending on temperature
Correct Answer: C
Solution :
Latent heat is used in increasing molecular separation. Length D shows heat absorbed during liquid to vapour change. So, length D is large.
