NCERT Solutions for Class 9 Science Chapter 1: Points to Remember

Below we have provided some of the important points to remember for NCERT Class 9 Science Chapter 1 to ace your exams:

  • Matter: Anything which has mass and occupies some space is called matter
    Solid, liquid and gas are not the substances but three different states of the same substance
  • Characteristics of particles of matter: The states of a substance differ with respect to interparticle spaces and intermolecular forces.
    The arrangement of the constituent particles is most ordered in solid state. It is comparatively less in the liquid state, while the particles can move quite freely in the gaseous state.
  • States of matter: Solids have fixed shape and definite volume.
    Liquids have definite volume but no fixed shape.
    Gases have neither fixed shape nor definite volume.
    The kinetic energy of particles is maximum in the gaseous state and minimum in the solid state.
    The diffusion of the gases varies inversely as the square root of their densities.
    Lighter gases can move upwards and heavier gases can move downwards.
    Gases can be compressed to a large extent by applying pressure.
  • Evaporation: Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon.
    Increase in the surface area increases the evaporation of a liquid.
    We perspire more on a humid day than on a dry day.
    Low boiling liquids evaporate faster than high boiling liquids
    Cooling is caused during evaporation and not during boiling.
