Question

name two types of forces which determines the physical state of substance

Answer 1

Answer:

The two types of forces which determine the state of substances are:–

• Force of Cohesion
• Force of Adhesion

Answer 2

The two types of forces that determine the physical state of the substance are:

1. Force of cohesion
2. Force of adhesion

Explanation:

Force of cohesion:

• It is an attractive intermolecular force that acts between the two portions of a similar substance.
• Hydrogen bonding and Vanderwal forces are responsible for the force of cohesion.

Force of adhesion:

• The attractive force which exists between different substances.
• They are also governed by hydrogen and Vanderwal forces.

However, thermal energy and inter-molecular attraction are responsible for determining the physical state of the substance.
