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 movely 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.
