  • Question 1
    CBSEENPH11017801

    Define interatomic forces and give an example?

    Solution
    The force between atoms of the molecule is called interatomic force.

    E.g.The nucleus and electron cloud of a molecule is binded by electrostatic force. 
    Question 2
    CBSEENPH11017803

    What do you understand by intermolecular forces?

    Solution
    Intermolecular force is the force between the molecules of the substance is called intermolecular force.
    There is a dipole-dipole interaction between the molecules.
    Question 3
    CBSEENPH11017804

    What is the force of adhesion?

    Solution

    Adhesive force is the attractive force between two unlike molecules. They are caused by forces acting between two substances like electrostatic force (attraction due to opposing charges), mechanical force etc. 

    E.g., Force of attraction between gum and paper.

    Question 4
    CBSEENPH11017806

    What is the force of cohesion?

    Solution
