    We can define motion as the change of position of an object with respect to time. A book falling off a table, water flowing from the tap, rattling windows, etc., all exhibit motion. Even the air that we breathe exhibits motion! Everything in the universe moves.

    During melting, the heat equal to latent heat of fusion and during boiling, heat equal to latent heat of vaporisation is used to overcome the inter particle force of attraction. Therefore, temperature remains constant.

    The key difference between compounds and mixtures is that a compound is made up of molecules, each of which is composed of two or more different types of chemically bound atoms. While the mixture is a combination of two or more elements or compounds that are combined physically rather than chemically.

    Account Deleted 1 year, 10 months ago

    His model failed to explain the stability of atoms. The arrangement of electrons in a circular path was not defined. Any particle that is moving in a circular path would undergo acceleration and radiates energy. Thus, the revolving electron would lose energy and finally fall into the nucleus.
