In this question, some of the properties are given.
00:04
We have to tell how does it changes according to intermolecular force strength.
00:15
So, first one is boiling point.
00:20
Strong intermolecular force require, strong intermolecular force require more energy to break the bonds between molecules and convert the substance from liquid to gas.
00:41
As a result, a higher temperature is needed to reach boiling point.
00:50
Therefore, the boiling point of substance increases with increasing intermolecular force strength.
00:57
Second one is viscosity.
00:59
Here stronger intermolecular forces leads to stronger attraction between molecules, making it more difficult for them to flow fast each other.
01:25
This results in thicker and more viscous substance.
01:37
Therefore, we can say that viscosity of substance increases.
01:41
Third one is surface tension.
01:44
Here strong intermolecular force cause the molecule at the surface of liquid to be more strongly attached to each other.
02:06
Sorry, it's attract to each other.
02:08
Creating a stronger surface tension and a more compact surface layer...
