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 substances but three different states of the same substance.
  • Characteristics of particles of matter: The states of a substance differ concerning interparticle spaces and intermolecular forces.
  • The arrangement of the constituent particles is most ordered in a solid state. It is comparatively less in the liquid state, while the particles can move freely in the gaseous state.
  • States of matter: Solids have fixed shapes and substantial volumes.
  • Liquids have definite volumes but no fixed shape.
  • Gases have neither a 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 to 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.
  • An increase in the surface area increases the evaporation of a liquid.
  • We sweat 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.

FAQs on NCERT Solutions for Class 9 Science Chapter 1

Some of the frequently asked questions on the NCERT Solutions for Class 9 Science chapter 1 are as follows:

Q: Where can I get NCERT Solutions for Class 9 Science?

Ans: Students can get chapter-wise NCERT solutions for Class 9 Science on Embibe.

Q: Is NCERT sufficient for Class 9 Science?

Ans: Yes, if students study from NCERT books and solutions, they can score good marks in the exams.

Q: Why does the temperature remain constant during the state change for any substance?

Ans: It is due to the latent heat. The heat supplied to increase the substance’s temperature transforms the substance’s state of matter; hence, the temperature stays constant.

Q: Are the NCERT Solutions Class 9 Science chapter 1 available for free?

Ans: Yes, the NCERT solutions are available for free on Embibe.

Q: What is CBSE Class 9 Science chapter 1 about?

Ans: CBSE Class 9 Science chapter 1 is about the matters in our surroundings. Students can learn about this chapter through free learning videos on Embibe.
